MOSIS - Affordable Integrated Circuits Fabrication
"MOSIS is operated by the Information Sciences Institute at the University of Southern California (USC). MOSIS merges multiple IC designs submitted by both companies and universities onto multi-project wafers (MPW) to share the cost of fabrication among multiple users."
MOSIS - Metal Oxide Semiconductor Implementation Service
MOSIS keeps the cost of fabricating prototype quantities low by aggregating multiple designs onto one mask set. This allows customers to share overhead costs associated with mask making, wafer fabrication, and assembly.
MOSIS Design Reference
A variety of design flows (digital, analog, mixed-signal) can be used with a number of different CAD tools, technology files, design kits, libraries and IP to create designs for processes accessed by MOSIS.
