MOSIS
MOSIS (Metal Oxide Semiconductor Implementation Service) is multi-project wafer service that provides metal–oxide–semiconductor (MOS) 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 University of Southern California's Information Sciences Institute (ISI), 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 ...

Multi-project Wafer Service
Multi-project chip (MPC), and multi-project wafer (MPW) semiconductor manufacturing arrangements allow customers to share mask and microelectronics wafer fabrication cost between several designs or projects. With the MPC arrangement, one chip is a combination of several designs and this combined chip is then repeated all over the wafer during the manufacturing. MPC arrangement produces typically roughly equal number of chip designs per wafer. With the MPW arrangement, different chip designs are aggregated on a wafer, with perhaps a different number of designs/projects per wafer. This is made possible with novel mask making and exposure systems in photolithography during IC manufacturing. MPW builds upon the older MPC procedures and enables more effective support for different phases and needs of manufacturing volumes of different designs/projects. MPW arrangement support education, research of new circuit architectures and structures, prototyping and even small volume production. W ...

Lynn Conway
Lynn Ann Conway (born January 2, 1938) is an American computer scientist, electrical engineer and transgender activist. She worked at IBM in the 1960s and invented generalized dynamic instruction handling, a key advance used in out-of-order execution, used by most modern computer processors to improve performance. She initiated the Mead-Conway VLSI chip design revolution in very large scale integrated (VLSI) microchip design. That revolution spread rapidly through the research universities and computing industries during the 1980s, incubating an emerging electronic design automation industry, spawning the modern 'foundry' infrastructure for chip design and production, and triggering a rush of impactful high-tech startups in the 1980s and 1990s."Lynn Conway: 2009 Computer Pioneer Award Recipie ...

Carver Mead
Carver Andress Mead (born May 1, 1934) is an American scientist and engineer. He currently holds the position of Gordon and Betty Moore Professor Emeritus of Engineering and Applied Science at the California Institute of Technology (Caltech), having taught there for over 40 years. He taught Deborah Chung, the first female engineering graduate of Caltech. He advised the first female electrical engineering student at Caltech, Louise Kirkbride. His contributions as a teacher include the classic textbook ''Introduction to VLSI Systems'' (1980), which he coauthored with Lynn Conway. A pioneer of modern microelectronics, he has made contributions to the development and design of semiconductors, digital chips, and silicon compilers, technologies which form the foundations of modern very-large-scale integration chip design. In the 1980s, he focused on electronic modelling of human neurology and biology, creating " neuromorphic electronic systems." Mead has been involved in the fou ...

Danny Cohen (engineer)
Danny Cohen (December 9, 1937 – August 12, 2019) was an Israeli American computer scientist specializing in computer networking. He was involved in the ARPAnet project and helped develop various fundamental applications for the Internet. He was one of the key figures behind the separation of TCP and IP (early versions of TCP did not have a separate IP layer); this allowed the later creation of UDP.''Where Wizards Stay Up Late: The Origins of the Internet'', by Katie Hafner and Matthew Lyon, 1996, Simon & Schuster, , pg. 236 Cohen is probably now best known for his 1980 paper "On Holy Wars and a Plea for Peace" Also published at ''IEEE Computer''October 1981 issue which adopted the terminology of endianness for computing (a term borrowed from Jonathan Swift's '' Gulliver's Travels''). Cohen served on the computer science faculty at several universities and worked in the private industry. Biography Cohen earned a bachelor's degree in mathematics at the Technion – Israel Ins ...

Integrated Circuit
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tiny MOSFETs (metal–oxide–semiconductor field-effect transistors) integrate into a small chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones and other home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs such as modern computer ...

Metal–oxide–semiconductor
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal-insulator-semiconductor field-effect transistor (MISFET) is a term almost synonymous with MOSFET. Another synonym is IGFET for insulated-gate field-effect transistor. The basic principle of the field-effect transistor was first patented by Julius Edgar Lilienfeld in 1925.Lilienfeld, Julius Edgar (1926-10-08) "Method and apparatus for controlling electric currents" upright=1.6, Two power MOSFETs in V_in_the_''off''_state,_and_can_conduct_a_continuous_current_of_30 surface-mount_packages._Operating_as_switches,_each_of_these_components_can_sus ...

Semiconductor Device Fabrication
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuit (IC) chips such as modern computer processors, microcontrollers, and memory chips such as NAND flash and DRAM that are present in everyday electrical and electronics, electronic devices. It is a multiple-step sequence of Photolithography, photolithographic and chemical processing steps (such as surface passivation, thermal oxidation, planar process, planar diffusion and p–n junction isolation, junction isolation) during which electronic circuits are gradually created on a wafer (electronics), wafer made of pure semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications. The entire manufacturing process takes time, from start to packaged chips ready for shipment, at least six to eight weeks (tape-out only, not including the circuit design) and is performed in highly specialized semiconduct ...
