Electronics industry braces for rare-earth-materials shortages

From EDN:

Electronics industry braces for rare-earth-materials shortages:

"China has started to severely restrict the exports of rare-earth materials, which often find use in “green”-technology designs, including hybrid vehicles and energy-efficient lighting, as well as in the medical, defense, and consumer markets. The country delivers nearly 100% of the world’s rare-earth materials: 17 metals that are somewhat hard to refine and that tend to occur in the same ore deposits (Table 1). The cutbacks have resulted in shock waves through the electronics industry and could force design changes in the near future.

Electronics industry braces for rare-earth-materials shortages table 1China set out on a moderate restriction path this year and then announced in July that it would cut exports by 72% for the remainder of 2010. It plans an overall export reduction of 30% for next year.

These cutbacks have increased the price of rare-earth materials an average of 700%, prompting legislation, which is currently stalled, to restart US rare-earth-materials production. The Western Hemisphere’s one rare-earth-materials producer, Colorado-based Molycorp Minerals, issued an initial public offering of stock in July, raising $390 million to restart its California mine and ramp up processing to counter world shortages.

Part of China’s motivation for reducing rare-earth-materials exports is its desire to emphasize its industrial status. China’s leaders want to move away from raw-materials exports and evolve toward exporting more finished goods.

Production of rare-earth materials fell off worldwide beginning in the 1980s when low prices in China made production unfeasible elsewhere in the world. Tom Valiere, senior vice president and co-founder of Design Chain Associates, says this cutback is a wake-up call for US industry. “We used to lead the world in the export of rare-earth materials,” he says. “In the last 20 years, we’ve become dependent. The whole thing flew under the radar until green technology placed demand on rare-earth materials and we realized they were sole-sourced to China.”

China’s restrictions this year have been part of a multiyear plan to save most of its supply for its own industry. “Each year, China has brought down its exports by X% and never exceeded its quotas,” says Gareth Hatch, co-founder of Technology Metals Research. “The reduction the country made in July was a huge reduction over the first half of the year.”

Worldwide shortages are now occurring. “The world outside China uses a collective 50,000 tons annually,” says Jim Simms, director of public affairs at Molycorp Minerals. “[China] reduced its exporting in 2010 to about 30,000 tons. Since China supplies about 97% of rare-earth materials, the world has to depend on what China exports.”

Simms believes that the demand for the materials will just increase over the coming years. The company expects to produce 20,000 tons by the end of 2012. “My BlackBerry only has about 3/10g of rare-earth materials,” he says, but “a single wind turbine requires about one ton. A car can use about 25 kg.”

Lynas Corp, a rare-earth-materials supply company in Australia, expects to increase rare earths delivery in 2011 to 11,000 tons per year.

Rare-earth materials facts

Rare-earth materials include terbium, which finds use in flat-panel TVs and high-efficiency fluorescent lamps, and neodymium, key to the permanent magnets in high-efficiency electric motors. Rare-earth materials are not indeed rare. The series of nonferrous metals is common in the environment. According to Design Chain Associates, most rare-earth materials are as common as copper, and even the rarest is more common than gold.

Part of the market pressure on rare-earth materials comes from new demand that green technologies has prompted. The market, including electric- and hybrid-vehicle motors and wind turbines, requires magnets.


The abstract submission for the 35th edition of the European "Workshop on Compound Semiconductor Devices and Integrated Circuits" (WOCSDICE 2011) is open.
The conference will be held in Catania (Italy), from  May 29th to June 1st 2011.

8.3% Efficiency in a OPV

I copy from their webpage:

Konarka's Power Plastic Achieves World Record 8.3% Efficiency Certification from National Energy Renewable Laboratory (NREL)

Lowell, Mass. - Nov. 29, 2010 - Konarka Technologies, Inc., an innovator in development and commercialization of Konarka Power Plastic®, a material that converts light to energy, today announced that the National Energy Renewable Laboratory (NREL) has certified that Konarka’s organic based photovoltaic (OPV) solar cells have demonstrated a record breaking 8.3% efficiency. This is the highest performance recorded by NREL for an organic photovoltaic solar cell.
"The progress Konarka has achieved this year with regard to solar cell efficiency is unprecedented, representing a significant milestone for the industry," commented Howard Berke, chairman, CEO and co-founder of Konarka. "This unsurpassed NREL certification opens new doors for the commercial production of cost-effective, efficient electricity for numerous large scale applications."
Konarka Power Plastic is a patent-protected thin film solar material that converts light to energy. The unique material is lightweight and flexible, lending itself to a wide range of applications where traditional photovoltaics are not effective.
The latest certification results are for Konarka’s large area single-junction solar cell with a surface area of 1 square centimeter. This efficiency rating far exceeds previous single-junction organic photovoltaic cell measurement on that surface area and represents the world record for OPV efficiency.

Shipments of silicon for semiconductor manufacturing raise more than 23%

I copy part of a post from EDN:

Shipments of silicon for semiconductor manufacturing in 2010 will grow by 23.6% year-over-year, reaching 8.9 billion total square inches, according to iSuppli estimates.

Global silicon shipments in terms of square inches are bouncing back in 2010, after suffering like most segments did in the 2008/2009 economy.

That's according to a report from iSuppli Corp, which estimated shipments will rise to record levels in 2010.

Shipments of silicon for semiconductor manufacturing in 2010 will grow by 23.6% year-over-year, reaching 8.9 billion total square inches, up from 7.2 billion square inches in 2009, iSuppli forecast. Growth is expected to continue and iSuppli projected that by 2014 12.4 billion total square inches of silicon will be shipped.

The gate tunnelling current of MOSFETs is an important factor in modelling ultra-small devices. In this reported work, the gate tunnelling current in present-generation MOSFETs is studied. Presented is a model for the gate tunnelling current in MOSFETs having ultra-thin gate oxides. In the proposed model, the electron wavefunction at the semiconductor-oxide interface is calculated and inversion charge by assuming the inversion layer as a potential well, including some simplifying assumptions. Then the gate tunnelling current is calculated using the calculated wavefunction. The proposed model results have excellent agreement with experimental results in the literature.

Accelicon Technologies, Inc. announces the market’s first commercially available Context Dependent Modeling Platform based on Accelicon’s flagship device modeling solution MBP. The performance of FETs can vary significantly, at advanced process nodes, due to layout dependent proximity effects. Sources of LDEs include Well Proximity Effect (WPE), lithography distortions, un-intentional stress sources such as Shallow Trench Isolation (LOD Effect) and intentional stressors which are used to enhance the performance of the device. These enhancement techniques include dual-stress liners, embedded SiGe and stress memorization techniques. At advanced process nodes engineers must analyze LDEs to minimize undesirable proximity effects and lithography distortions, and effectively utilize stress enhancement techniques. This analysis can only be conducted after layout extraction, SPICE modeling alone is not sufficient.

LDMOS - Technology and Applications

Speaker: Shekar Mallikarjunaswamy, Alpha Omega Semiconductor
Date: Sept 14th, 2010
Location: National Semiconductor, Building E1, Conference Center, 2900 Semiconductor Drive, Santa Clara , CA 95051 .

Abstract: A key device that is used in most high voltage (20 to 120V) power integrated circuits for power management applications is the Lateral Diffused MOS (LDMOS) transistor. Recent interest in ‘green” products have further increased the demand for integrated HV LDMOS devices in CMOS and BCD technologies to build higher efficiency dc-dc converters for consumer and LED markets. This presentation will journey through the structural innovations from “planar” to “trench” and to state-of-the-art “RESURF” LDMOS devices in both junction and dielectric isolation technologies for the past two decades. The physics of operation, figure of merits used for device comparison, layout techniques including integration of LDMOS into modern CMOS/BCD technologies will be discussed. Device and process simulations to optimize device parameters including SPICE macro circuits to model “quasi-saturation” and “Cgd” capacitance will be described. Methods to improve hot carrier reliability and ESD robustness of LDMOS devices will be highlighted. Finally, LDMOS circuit topologies and their applications in consumer, computer and telecommunication products will be presented to let the audience comprehend and appreciate the significance of LDMOS devices to modern power management products.

Modeling Memristor with SPICE

In 1971, Professor Chua proposed [1] that by necessity of symmetry reasons, besides the resistor, the capacitor, and the inductor; a fourth circuit element has to exist. In 2008, members of an HP Lab published [2] that they successfully realized a nano-scale electronic component. Spice macromodel [3-6] could be a powerful tool for electrical engineers to design and experiment new circuits with memristors.

How To Make a P-N-P-N Semiconductor Device

50 years ago this year, in its 'Patent Pointers' section, the Electronics Weekly edition of September 14th 1980 carried the following snippet.

'An ingenious way of making a P-N-P-N or an N-P-N-P semiconductor device which avoids the difficulty of the heat treatment of the second junction adversely affecting the first formed junction is described in Patent No. 844970, filed by British Thomson-Houston Co.'

The note continues:
'What is done is to form a first P-N junction by alloying semiconductor germanium of N type with semiconductor silicon of P type, the second junction being subsequently made by fusing indium to the germanium.'

The note ends:
'The second junction is made at a lower temperature than the first so that the first junction is unharmed.'

Therefore, candidates from European countries can apply for an Intra European Fellowship and candidates from outside Europe can apply for an International Incoming Fellowship.These felowships can be for one or two years. Salaries are extremely good and the prestige of having this type of fellowship is very high. For this reason, there is a tough competition to get these fellowships.I am looking for candidates for these Marie Curie Grants, both from Europe and outside Europe. Candidates must have a good CV (preferably with more than 4 publications in international journals, in order to have chances).

In order to fit the Marie Curie requirements, their age should be below 35.

If successful, the postdoctoral researchers will work on the characterization of compact modeling of any of the advanced semiconductor devices targeted by our research European projects: nanoscale MOSFETs, SOI and Multi-Gate MOSFETs, strained-Si/SiGe MOSFETs, Schottky-Barrier MOSFETs, nanowire FETs, III-V HEMTs and organic TFTs.The specific device/s in which the postdoctoral researcher will work will depend on his/her preference and background.

Candidates must send me by e-mail (to a CV or resume by AUGUST 14. Successful applicants will be informed by August 15, and then we will start to make the application. The successful candidates will be informed on the steps to do.

Tarragona is a small city (110000 inhabitants) on the Mediterranean coast, about 100 Km south from Barcelona, and very well connected to Barcelona and the main Spanish cities by rail and highway. Tarragona is a very old city, very important during the Roman Empire, and with a lot of historical landmarks.The quality of life in Tarragona is excellent. Mediterranean and mild climate the whole year. Wonderful beaches around the city (even at the city). Mountains close to the city (even the Pyrenees are not far). Besides, the city is very quiet, but with an intense nightlife.

My research group in the Department of Electronic Engineering, Universitat Rovira i Virgili (URV) is one of the strongest groups in compact modeling in Europe. We are leading one European project on compact modeling (in which a total of 15 European universities and companies participate). We also participate on two other European projects (one about nanoscale MOSFETs and another one about organic Thin Film Transistors). I am looking forward to receiving excellent applications!
