Chinese operations select UltraFLEX, J750 Teradyne has announced the sales of semiconductor test systems to three companies operating in China. First, Shanghai-based Semiconductor Manufacturing International Corporation (SMIC) has selected UltraFLEX test systems for high-volume wafer testing. Teradyne reports that SMIC will use the UltraFLEX ( pictured ) to test audio, ......
- Silicon Debug
For reasons of cost, performance, power, and miniaturization, many electronic systems that once consisted of several printed circuit boards are now manufactured as a single semiconductor device. As a result of this complexity, previously accessible system signals can no longer be observed, and the process of isolating and analyzing silicon ......

STS purchases multiple Octet systems Credence Systems (Fremont, CA) has announced that Silicon Turnkey Solutions (STS, Manteca, CA) has purchased multiple Octet system-on-chip (SOC) test systems. STS, an outsource assembly and test (OSAT) provider, will use the systems for test-program generation, engineering development, silicon debug, and volume manufacturing. The Octet's ......
- Genesis Microchip yields visible gains with real-time information access
Making a profit in the semiconductor business necessitates staying on top of yield —i.e., the proportion of sellable product in every production batch. In semiconductor manufacturing, yield can run from 70 percent to 90 percent, but poor yield at one step can snowball through further stages of the manufacturing process....
- In Situ Particle Detection for Pre-Metal Sputter Etch
Particle control during wafer processing continues to be a critical factor in the successful production of semiconductors. Although cleanroom particle control has matured with the implementation of fully automated wafer handling systems, the major source of yield-limiting particle events — the actual wafer processing environment — continues to create particle ......
- Detection and classification of defect patterns on semiconductor wafers.
1. Introduction The manufacture of integrated circuits is a complex and costly process that involves hundreds of steps and requires the monitoring of many process parameters throughout the production process. Today, even using highly automated and precisely positioned equipment located in a near-dust-free clean room and operated by well-trained process ......
- E-Manufacturing: The Evolution Continues
It should be no surprise that a semiconductor manufacturing fab is loaded with computer power. At the fab level, a computer-integrated manufacturing (CIM) system is coupled with manufacturing execution software (MES) to track lots, manage recipes and monitor the status of tools. What may be surprising is the lack of ......
