Sematech: Purpose and Performance

High-performance special-purpose computers in science

The next decade will be an exciting time for computational physicists. After 50 years of being forced to use standardized commercial equipment, it will nally become relatively straightforward to adapt one's computing tools to one's own needs. The breakthrough that opens this new era is the now wide-spread availability of programmable chips that allow virtually every computational scientist to d...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...

Binning for IC Quality: Experimental Studies on the SEMATECH Data

Screening based on the locality of defects has long been informally practiced in the industry, whereby die from wafers, or parts of the wafer, that display a high incidence of failures are discarded. More recently we have refined this approach such that tests results for neighboring die on the wafer are also considered in evaluating test results for a particular die [l ]. It has been shown [2-4...

High-tech R&D subsidies Estimating the effects of Sematech

Sparked by concerns about their shrinking market share, 14 leading U.S. semiconductor producers, with the financial assistance of the U.S. government in the form of $100 million in annual subsidies, formed a joint R&D consortium Sematech in 1987. Using Compustat data on all U.S. semiconductor firms, we estimate the effects of Sematech on members’ R&D spending, profitability, investment, and pro...
