MOSIS


MOSIS provides metal–oxide–semiconductor chip design tools and related services that enable universities, government agencies, research institutes and businesses to prototype chips efficiently and cost-effectively.
Operated by the , MOSIS combines customers' orders onto shared multi-project wafers that speed production and reduce costs compared with underutilized single-project wafers. Customers are able to debug and adjust designs, or to commission small-volume runs, without making major production investments. Fabrication costs are also shared by combining multiple designs from a single customer onto one "mask set," or wafer template. According to MOSIS, the service has delivered more than 60,000 integrated circuit designs.
MOSIS was created in 1981 by ISI's Danny Cohen, an Internet pioneer who also developed Voice over Internet Protocol and Video over Internet Protocol. It was based on the inventions of VLSI pioneer Lynn Conway, who invented and tested this new approach to rapid-prototyping and short-run fabrication at Xerox PARC. One of the first e-commerce providers, MOSIS also launched the "fabless foundry" industry, in which vendors outsource chip orders rather than relying on their own factories. Thousands of students also have learned chip design in MOSIS-associate programs.
Many early MOSIS users were students trying IC layout techniques from the seminal book Introduction to VLSI Design published in 1980 by Caltech professor Carver Mead and MIT professor Lynn Conway. Some early reduced instruction set computing processors such as MIPS and SPARC were run through MOSIS during their early design and testing phases.
