Updated International Technology Roadmap for Semiconductors Explores Key Issues and Trends Through 2018
SAN JOSE, CALIF. — The Semiconductor Industry Association (SIA) has released the 2003 edition of the International Technology Roadmap for Semiconductors (ITRS). The ITRS reaches into the future to 2018, exploring key issues and trends in semiconductor technology. The purpose of the ITRS is to provide a reference of requirements, potential solutions and their timing for the semiconductor industry. This is accomplished by providing a forum for international discussion, cooperation and agreement among leading semiconductor manufacturers and equipment suppliers, software suppliers, and researchers from universities, consortia and government labs.
“The global, cooperative efforts of the ITRS have fostered collaboration among international consortia, universities and research institutions around the world,” says SIA.President George Scalise. “We hope that the 2003 ITRS will further contribute to shared R&D investments so that the financial weight of pre-competitive technologies can be equitably shared by the whole industry.”
“A big issue during the formulation of the 2003 ITRS.was whether 2003 or 2004 would be the year of production for the 90-nm technology node,” says Robert Doering, Texas Instruments' senior fellow, Silicon Technology Development. “The conclusion was to leave it in 2004, a return to a 3-year-per-node pace.”
SIA collaborated on the ITRS with International SEMATECH.
A copy of the 2003 ITRS is available on the Web — http://public.itrs.net/.

Tessera Licenses Advanced Packaging Technology to Oki
SAN JOSE, CALIF. — Tessera Technologies Inc. and Oki Electric Industry Co. Ltd. (Tokyo, Japan) have signed a licensing agreement. Oki and their subcontract assemblers plan to use Tessera's semiconductor packaging technology in devices such as microcontrollers and ASICs.
The technology available to Oki under this license covers a broad range of chip scale and multichip package types, including IC devices packaged in “face-down,” “face-up,” “fold-over,” “stacked” and “system-in-package” (SiP) formats, using many different types of materials, including packages using either tape and laminate substrates. These package types are marketed by Tessera as MicroBGA for face-down orientations, MicroBGA-F for face-up orientations, and MicroZ for multichip solutions.
Oki is the tenth Japanese semiconductor company to become a Tessera customer, according to the company.
In other Tessera news, 2003 was a record year for the company. They finished off the year with $37.3 million in total revenue, up from $28.3 in 2002.
Amkor Sees Surge in Demand for Stacked Packages
CHANDLER, ARIZ. — Amkor Technology Inc., citing accelerating demands for advanced packaging solutions for cell phones and other handheld applications, is expanding capacity for stacked chip scale packages (S-CSPs). Amkor's factories in Korea and Japan already produce stacked packages, and the company plans to install S-CSP capacity in its factories in Taiwan and China.
With nearly 50 million S-CSPs shipped last year, Amkor expects production capacity to approach 50 million per quarter (depending on die-stack configuration) by the middle of 2004. The company's stacked packages, containing three or more active chips, accounted for more than 20 percent of its total S-CSP production in the fourth quarter of 2003. During 2003, Amkor's production of 3+ S-CSP rose to nearly four million in the fourth quarter from approximately 20,000 in the first quarter.
Amkor attributes its success with advanced die stacking to process expertise in wafer thinning, advancements of wire bonding and development of film-based die-attach and spacer technologies.
New Player in the MEMS Arena
BY JULIA GOLDSTEIN
MONTREAL, QUEBEC — Microbridge Technologies, a start-up company specializing in micro-systems technology, recently unveiled a fascinating new product at IEEE MEMS 2004 (January 25-29 in Maastricht, The Netherlands) — an adjustable micro-resistor they call the Rejustor. The device is based on conventional silicon IC technology, with a micro-heater embedded in a thermally isolated membrane suspended over a cavity in a silicon chip. The Rejustor allows precision electrical “trimming” of resistance values without the use of a laser. All adjustments can be carried out at low voltage and low current before or after packaging or even in-circuit after years of operation. The micro-resistors are particularly interesting for RF applications as passive adjustable resistors with low capacitance and excellent high-frequency performance.
Les Landsberger, Microbridge's chief technology officer, explained some of the adjustable-resistance capabilities, “Pairs of Rejustor devices can be resistance matched to typically better than 0.005 percent and their temperature coefficient of resistance (TCR) can be adjusted to match another Rejustor to better than 2 ppm/°K. Or it can be adjusted to a precise mismatch in TCR to help temperature compensate electronic circuitry.”
“The combination of precision resistance adjustment and TCR matching or controlled TCR mismatch provided by the Rejustor takes analog and sensor design beyond today's capabilities to the next stage of precision performance over wide temperature ranges” said Nick Tasker, newly-appointed VP of Business Development at Microbridge. “A new generation of high-performance semiconductor IC devices is now possible.”
Devices will be available in discrete form or can be incorporated into analog, mixed-signal and system-on-chip IC designs. Microbridge announced in January that they have chosen X-FAB Semiconductor Foundries AG, of Germany, for the initial manufacturing of the Rejustor.
In December 2003, Microbridge announced the appointment of Dr. Adam Chowaniec as the chairman of the company's board of directors. “We are fortunate to be able to attract a chairman with Chowaniec's experience to our board of directors,” said Mike Foster, president and CEO of Microbridge Technologies.
Microbridge Technologies looks like a company to watch.
