A third-consecutive month of growth in semiconductor sales has the SIA cautiously optimistic about an industry recovery, though shied away from calling the next upturn. Worldwide sales of semiconductors in May rose to US$16.5 billion, an increase of 5.4% from April’s figure of US$15.6 billion. Read more >>

Eyelit, Inc. has shipped one of its integrated manufacturing execution software (MES) suites to materials technology company Umicore for production of germanium wafers at its Olen, Belgium-based Electro-Optic Materials Business Unit. The company intends to roll out the system to Quapaw, Oklahoma in the second half of this year. Read more >>

Elpida Memory, which operates one of the world’s largest DRAM memory fabs in Hiroshima, Japan, will undergo a major internal transformation as the company battles a continued over capacity in the memory markets and seeks Japanese Government funds to continue operations. Elpida said it would divide the massive facility into two separate lines, one dedicated to mobile device-related DRAM and the other to PC related DRAM devices. Both lines will have their own management teams and operate separately, the company said. Read more >>

By Ernst Richter et al - ABSTRACT - This article follows up on a previously published paper that introduced the 110nm technology transfer of Dynamic Random Access Memory (DRAM) for the Inotera Memories joint venture at start-up [1]. In this paper, technology transfer and ramp of the 75nm DRAM technology is outlined for Inotera in full production mode. Again, technology transfer was done from Qimonda (previously Infineon Technologies) at Dresden in Germany where the technology was jointly developed with Nanya Technologies. Inotera at Taoyuan in Taiwan was the first receiving site to repeat the technology qualification. Continuous sales price reduction puts pressure on memory firms for fast introduction of technology shrinks to remain cost competitive [2]. Delays as short as a few days in the production ramp can translate into millions of dollars of missed opportunity in revenue. This paper sets forth the steps taken by the two companies to avoid such setbacks in the technology transfer. Read more >>

By Brandon Lee & Susanta Dash, CIMAC, San Jose, California, U.S. - ABSTRACT - Performance testing is carried out on an MES system to identify and eliminate bottlenecks that can potentially cause production outages and lost revenue in a semiconductor production fab. In a distributed system, bottlenecks can occur at the client site, within the server or in the  network. The MES system is the heart of the manufacturing operation and interacts with a number of other systems to support the manufacturing line in a fab. As production increases with ramping up of the production volume, the loads on the various systems that support the production also increase. This paper puts forward the potential benefits in applying the MES system for testing and validation of performance and scalability to measure the various key parameters, thus providing good ROI by early detection of potential problems.
