Professor settles with Mitsubishi in LED/LD patent dispute

Posted by: admin  :  Category: Semiconductor Industry

NEW YORK, USA: Prof. Gertrude Neumark Rothschild has reached a settlement with Mitsubishi Corp. regarding her assertion that the company and dozens of other major electronics manufacturers in Asia and Europe violated her patents for producing light emitting diodes and laser diodes in products, such as video players that are used for Sony’s Blu-ray format, Motorola Razr phones and Hitachi camcorders, backlighting for computers, as well as street lighting and optical storage of information.

Mitsubishi is the latest company to reach a global settlement with Rothschild, a professor emeritus at Columbia University. Others who have settled include BenQ, Dalien Lumei, Epistar Corp., FOREPI, Guangzhou Hongli, Hitachi, Hugo Optotech, LG, Motorola, Pioneer Corp., Samsung Electro Mechanics, Samsung Electronics, Sanyo Electric, Sewa Electric, Sharp Corp., Shenzhen Unilight, Showa Denko, Sony Corp., and Sony Ericcson. Earlier settlements were made with Nichia Chemical and Koninklijke Philips Electronics, which included Philips Lumilid Lighting Co. and Toyoda Gosei Co. Ltd.

Terms of the Mitsubishi agreement are confidential, according to Rothschild’s attorney, Albert Jacobs Jr. of Troutman Sanders LLP. However, the aggregate received from her settlements and licenses — which now have been concluded with more than 40 companies — amounts to over $27 million, Jacobs said.

“Dr. Rothschild made a seminal breakthrough in the production of LEDs and LDs, especially the blue, violet and ultraviolet LEDs that are essential to a wide variety of consumer electronics products today,” said Jacobs. “She richly deserves both scientific as well as commercial recognition for her work.”

Prof. Rothschild, who is the sole owner of US Patent Number 5,252,499, as well as the recently expired ‘618 patent and foreign patents related thereto, is currently Howe Professor Emeritus of Materials Science and Engineering at Columbia.

She conducted ground-breaking research in the 1980s and 1990s into the electrical and optical properties of so-called wide band-gap semiconductors. This research has proven pivotal in the development of short-wavelength emitting (blue and violet) diodes that are now widely used in consumer electronics.

She was issued two US patents in the early 1990s that cover methods of producing wide band-gap semiconductors for LEDs and LDs. Such LEDs and LDs have become increasingly popular in a variety of devices as a superior lighting source because of their reduced power consumption, greater reliability, longevity and greater storage capacity.

Recognized by the American Physical Society as a Notable Woman Physicist in 1998, Professor Rothschild was elected as a Fellow of the American Physical Society in 1982.

Prof. Rothschild began her research career in private industry, working with Sylvania Research Laboratories in Bayside, N.Y., in the 1950s, and later at Philips Laboratories in Briarcliff Manor, N.Y. She joined the faculty at Columbia University as a Professor of Materials Science in 1985. In 2008, she was selected as a recipient of Barnard College’s Distinguished Alumna Award. She has published approximately 90 research articles and given 28 invited talks since 1980.

Inertial MEMS accelerometers That are 1000 Times more Sensitive will benefit applications such as bridge, infrastructure and seismic monitoring

Posted by: admin  :  Category: Technology

HP today announced new inertial sensing technology that enables the development of digital micro-electro-mechanical systems (MEMS) accelerometers that are up to 1,000 times more sensitive than high-volume products currently available.

A MEMS accelerometer is a sensor that can be used to measure vibration, shock or change in velocity. By deploying many of these detectors as part of a complete sensor network, HP will enable real-time data collection, management evaluation and analysis. This information empowers people to make better, faster decisions, and take subsequent action to improve safety, security and sustainability for a range of applications, such as bridge and infrastructure health monitoring, geophysical mapping, mine exploration and earthquake monitoring.

The HP sensing technology enables a new class of ultrasensitive, low-power MEMS accelerometers. Up to 1,000 times more sensitive than high-volume, commercial products, sensors based on this technology can achieve noise density performance in the sub 100 nano-g per square root Hz range to enable dramatic improvements in data quality. The MEMS device can be customized with single or multiple axes per chip to meet individual system requirements.

The sensing technology is a key enabler of HP’s vision for a new information ecosystem, the Central Nervous System for the Earth (CeNSE). Integrating the devices within a complete system that encompasses numerous sensor types, networks, storage, computation and software solutions enables a new level of awareness, revolutionizing communication between objects and people.

“With a trillion sensors embedded in the environment – all connected by computing systems, software and services – it will be possible to hear the heartbeat of the Earth, impacting human interaction with the globe as profoundly as the Internet has revolutionized communication,” said Peter Hartwell, senior researcher, HP Labs.

 

 


Legislative update – Sept. 2009 — REACH, RoHS2

Posted by: admin  :  Category: Semiconductor Industry

Guest post by Gary Nevison, Farnell

Summary
The legal obligations within the REACH Regulations and the potential impact of the so called “RoHS2” proposals dominate the legislative scene at present. Also, obligations are starting to filter through as part of the eco design/energy using Products Directive that monitors energy efficiency throughout a products life cycle. Going-forward, the scope of this directive will become more diverse to encompass energy related products.

Industry, and the design engineer, needs to be aware of developments and the potential impact on their companies.

REACH
Regulation 1907/2006, the Regulation, Evaluation, Authorisation -and restriction-of Chemicals (REACH) entered into force on 1 June 2007 after almost 8 years of debate and covering some 849 pages of regulation.

The only census on chemicals, taken in 1981, highlighted that 100,106 substances were placed on the market. Of those used, manufactured or imported at levels of 1000 tonnes or more, 21 percent had no safety data at all while a further 65 percent provided insufficient safe use data. Only 3 percent had been fully tested.

At the same time, instances of allergies, asthma, certain types of cancer and reproductive disorders were on the increase in Europe. Skin diseases alone resulted in the loss of 3 million working days per year.

Driven by the obligatory flow of safety data throughout the supply chain, REACH seeks to provide protection to health and the environment.

The biggest challenge to industry to date has been around the collection of data advising where a so called Substance of Very High Concern (SVHC) is present in a product, known as an article in the regulations, at a level of 0.1% by weight of the total article.

As a minimum obligation the name of the substance along with supporting safe use data must flow downstream through the supply chain.

Substances that are categorised as SVHC include those that are carcinogenic, mutagenic or toxic for reproduction. Also, substances that are persistent, liable to bio-accumulate and toxic, and finally “others” such as endocrine disrupters that can have a particular impact on aquatic life.

Back in October 2008, the first batch of 15 substances of very high concern was published by the European Chemicals Agency and, the following January, seven of these were earmarked for a consultation on whether or not they should be subject to a very costly “authorisation of use” requirement. These seven were approved and the European Commission will determine the date when these will be added to Annex XIV.

These obligations will then enter into force some 42-48 months later on what is known as the sunset date. Where such an authorisation is approved, downstream users can only use these substances for the use that they have been authorised for and they can only be purchased from the company granted the authorisation.

The REACH data collection has resulted in the circulation of hundreds of “standard letters” in a multitude of formats. Many manufacturers have refused to reply to the ad-hoc requests they receive preferring to promote websites or central databases (these have been slow to develop).

Guidance on the regulation encourages a more pro-active approach rather than simply providing a link to a website. Likewise, there have been many random requests for information that is not obligatory such as pre-registration details and RoHS style certificates of compliance.

Future batches of SVHCs will be published on an on-going basis, with the next expected early 2010, so REACH will not be a box that can be ticked as complete for several years to come.

“RoHS2”
Looking back the Restriction of Hazardous Substances (RoHS) Directive 2002/95 entered into force on 1 July 2006. It featured six restricted substances across eight broad categories of product pulled from the 10 categories in the Waste Electrical and Electronic Equipment (WEEE) Directive. There were 29 exemptions to assist manufacturers and design engineers where no viable alternative was available and a whole raft of “grey” definitions that required clarity.

“RoHS2” proposals look to move the directive forward and provide greater clarity. However, some of its provisions will potentially have cost and resource issues for industry.

The proposals recommend that the two remaining categories from the original WEEE categories, namely medical devices and monitoring and control instruments be added to the scope from 2014 (in-vitro diagnostics from 2016 and industrial “test” equipment in 2017). These were originally omitted from the directive due to reliability concerns over the use of lead-free solder.

While there are no substances actually restricted under the proposals, four are recommended for priority assessment. Three plasticisers used in a variety of applications and a flame retardant may well be restricted. Ironically, the substances, BBP, DBP, DEHP and HBCDD are four of the seven subject to authorisation of use under the REACH Regulations.

The fate of these substances under RoHS will be open to consultation after the revised directive comes into scope sometime in 2011-2012. Either way, any restriction under RoHS will probably be sooner than under the REACH process and the analysis is unlikely to be done twice.

Under a separate review by European Commission consultants, 29 exemptions will continue under the proposals, many with amended wording for clarity, 6 will be withdrawn and one new one will be granted. These could come into force next year and that will be followed by a transposition period of, on average, 18 months allowing manufacturers the time to comply.

In addition, a further six exemptions were added in June 2009 that had been proposed a year earlier.

RoHS2 also clarifies definitions such as equipment within out of scope equipment, spare parts and military where the latter clearly does not include dual use equipment.

A standard, and rigid declaration of conformity appears in annex 7 and will replace the multitude of different certificates, statements and compliance documents under the original legislation.

There now appears to be no scope for qualifying statements such as “so far as we are aware” and “to the best of our knowledge”.

It is proposed that RoHS will become a CE mark directive placing responsibilities on manufacturers, importers and distributors. There are many requirements including building technical files and keeping for 10 years, ensuring products comply, that they are supplied with the CE mark and the manufacturer or importer is identified on the product. Sample testing should also be carried out where appropriate, and corrective action is undertaken where product is found to be non compliant.

Finally under the proposals, the broad product categories and list of indicative products move from the WEEE Directive and sit in annex 1 and 2 of the RoHS Directive.

The terminology “RoHS2” is unofficial and is used simply to highlight the proposed changes to the original directive.

Energy using Products
Directive 2005/32/EC, Energy using Products, entered into force on 11 August 2007.

The main aim is to monitor energy efficiency throughout the life cycle of a product from the mining of raw material right through to recycling at end-of-life.

The focus is clearly on the design phase of the product since it is considered that this is the determining stage affecting the resources used in a product.

The directive does not apply to means of transport (planes, cars etc) but, apart from this, the scope is deliberately broad covering, in principle, any product which when in use depends on, generates, transfers or measures energy (electricity, fossil fuel or renewable).

Obligations on manufacturers will result from a series of specific “implementing measures” the first of which was adopted in January 2009.

The criteria required before a product can be considered for assessment is that is that it must sell more than 200,000 units per year in the European Union, have a significant environmental impact and present considerable potential for improvement. The latter is important as the target is for a 20% improvement in energy efficiency by 2020.

During phase one, studies were commission on 20 broad product categories ranging from water heaters, televisions and lighting, through to imaging equipment and personal computers.

Beyond that, a further 17 categories have been highlighted from ovens and hobs, machine tools and air-conditioning equipment through to transformers and networking equipment.

Among the first obligations to come in to force were energy efficiency improvements covering standby and off-mode losses, simple converter boxes for digital television, external power supplies and office, street and domestic lighting.

However, the European Parliament has now adopted the European Commission’s (EC) proposal to widen the scope of the directive to include energy related products. Until now the Energy using Products Directive was limited to products that consume energy during use such as boilers, computers, televisions, industrial fans and light bulbs.

However, many products have an indirect impact on the energy in use such as water using devices, taps and showerheads for example, and double glazing windows or insulating material.

Improvement in design could clearly result in the significant saving of energy.

For example, water saving taps and shower heads reduce water consumption and therefore the amount of energy used for hot water.

Under the EuP Directive studies had to set requirements for individual products where, in fact, it is the performance of the whole system that often needs to be optimised not just a single component or products.

The new directive will repeal the existing 2005/32/EC.

Intel and Sun Micro Product Roadmap Updates

Posted by: admin  :  Category: Technology

Intel will use its upcoming Intel Developer Forum to highlight several key developments in its product roadmap — starting with smaller, more efficient chip designs and specialized applications for its Nehalem line.

* Intel will show off “Westmere,” the first processors built using a 32 nanometer (nm) manufacturing process.
* CPU manufacturing shrank from 65nm to 45nm to 32nm and next to 22nm.
* The next chip architecture will come in 2010, in the form of the new architecture codenamed “Sandy Bridge,” which will also be disclosed at this month’s IDF. Intel’s roadmap is process shrinkage and then better architecture and then process shrink etc… (tick-tock)
* This new-generation high-k metal gate transistor formula will give Intel “a 3+ year advantage in addressing leaky and energy inefficient transistors,” according to a blog post from Intel spokesman Bill Kircos Intel has shipped >200 million 45nm CPUs using high-k+ metal gate transistors.
* For the first time, Intel has developed a full-featured SoC process technology to complement the CPU-specific technology. This version is for our smarter System on Chip (SoC) product efforts, which emphasize lower power transistors
* Intel NMOS transistors now have 19% performance improvement over their 45nm counterparts and our PMOS transistors now have a 28% performance improvement over their 45nm counterparts.
* Another IDF highlight: Nehalem-based chips codenamed “Jasper Forest” and designed for the embedded and storage sectors. This family of products will bring Nehalem to the embedded market, offering integrated PCI Express (PCIe) and an integrated I/O hub in a dual-processor Xeon processor.
* Nehalem will allow for much faster and denser storage and communications solutions such as IPTV, VoIP, NAS, SAN and wireless radio network controllers

The UK Register has information on the Sun Sparc Roadmap. The 16-core “Rock” UltraSparc-RK processor for Sun’s once-and-never “Supernova” line of servers is not on the roadmap. The one-page roadmap is one given Sun’s customers – and presumably also Fujitsu’s customers – have been shown about the future Sparc processor lineup.

June 2009 Sun Roadmap

A long way off in late 2010 or early 2011, the Sparc Enterprise server lineup gets a speed boost to 3 GHz with the Jupiter-E chips.

After that, in 2012, Sun has made no commitment to the kicker line of Fujitsu “Advanced Product Line 2″ servers coming from Fujitsu. These APL2 machines are presumably to be based on the “Venus” eight-core Sparc64-VIII processor, which has a Sparc64-VIIIfx variant aimed at supercomputers. That Sparc64-VIIIfx chip will be used in a 10 petaflops massively parallel machine being built by Fujitsu and paid for by the Japanese government under the 1.2bn Project Keisoku effort.

All of this is subject to change, and some of it most certainly will once Oracle takes control of Sun.
