Heard on the Beat (July 13) Commentary & analysis of week's chip news Applied offers deep-trench silicon etch chamber for sub-100-nm DRAM processes SANTA CLARA, Calif.--Applied Materials Inc. today announced a new silicon etch chamber for 200- and 300-mm wafer DRAM fabs needing deep-trench etching technology for 100-nm and below process geometries. TEL enters integrated metrology market with technology for 0.10-micron devices TOKYO -- Bearing the first fruit from its recent acquisition of Timbre Technologies Inc., Japan's Tokyo Electron Ltd. (TEL) here today entered the integrated metrology market by announcing a new technology for use in devices at the 100-nm node and below. TEL's so-called Optical Digital Profiling (ODP) technology enables the development of advanced, integrated metrology capabilities for its various tools. The Japanese chip-equipment giant plans to integrate this technology in its etchers, wafer track, and other systems by the middle of 2002. Hynix moves closer to wafer-level test of fast DRAMs SEOUL -- Korea's Hynix Semiconductor Inc. has demonstrated the ability to perform high-speed wafer-level testing of DRAM devices using a probe system from Teradyne Inc. and probe cards from FormFactor Inc., the companies announced today. DSP Group to license Siliver baseband processor next-generation GSM handsets SANTA CLARA, Calif. -- DSP Group Inc. here announced it will license a combination baseband processor/radio-frequency (RF) core for next-generation handsets based on the global system for mobile communications (GSM) standard. Co-Developed by DSP Group and a French design house called Stepmind, the Silver-1 core enables systems manufacturers to build a dual-mode handset based on the GSM/GPRS/EDGE standards. Rambus slashes royalty rate for SDRAM customer Rambus Inc. for the next year will allow a "major (synchronous DRAM) licensee" --- believed to be Samsung Electronics Co. --- to make single reduced quarterly payments instead of paying royalties, company officials revealed Thursday in the conference

DRAM and SDRAM Memory Chips
Dynamic random access memory (DRAM) chips are single-transistor memory cells that use small capacitors to store each bit of memory in an addressable format that consists of rows and columns. Because capacitors are unable to hold a charge indefinitely, DRAM memory chips require a near-constant pulse of current to retain stored information.
Photolithography services create photomasks and use them to etch or engrave patterns on semiconductor substrates.
Lithography equipment transfers circuit or device patterns onto a substrate using a patterned mask and a beam of light or electrons to selectively expose a photoresist layer. Overlay metrology systems align the pattern masks or reticules.
GPRS chips use general packet radio service (GPRS), a standard for wireless communication with a throughput rate of 115 kilobits per second.
Bluetooth® chips are board level components which broadcast in the 2.4 GHz industrial, scientific, and medical (ISM) radio band.
