LONDON – Tower Semiconductor Ltd., a specialty foundry that trades under the name TowerJazz, has transferred a 130-nm silicon-germanium process from its Newport Beach fab to one at Migdal Haemek, Israel.
Tower said the SBL13 process as heavily analog that uses SiGe bipolar for the analog and CMOS for digital control and that it had enhanced the process with a copper interconnect back-end. The process is aimed at wireless RF and digital TV tuners. Tower said it has design wins from customers that want to use the copper back-end and that volume is expected to ramp in the first half of 2012.
The SBL13 process includes three NPN transistors with 40-, 74- and 100-GHz transition frequencies as well as high density passive elements such as high-density MIM capacitors and 3-micron thick copper inductors. 130-nm CMOS with copper metallization achieves digital logic densities of up to 200-kgates per square millimeter to result in higher performance and more highly integrated RF products.
"This helps extend our leadership in SiGe technology and provides a unique multi-fab SiGe sourcing capability for our customers," said Marco Racanelli, senior vice president and general manager of the RF and high performance analog business group at Tower, in a statement.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
