Frank Wanlass
Frank Marion Wanlass (May 17, 1933 in Thatcher, AZ – September 9, 2010 in Santa Clara, California) was an American electrical engineer. He is best known for inventing CMOS (complementary MOS) logic with Chih-Tang Sah in 1963. CMOS has since become the standard semiconductor device fabrication process for MOSFETs (metal-oxide-semiconductor field-effect transistors). Biography He obtained his PhD from the University of Utah. Wanlass invented CMOS (complementary MOS) logic circuits with Chih-Tang Sah in 1963, while working at Fairchild Semiconductor.

General Microelectronics
General Micro-electronics (GMe) was an American semiconductor company in the 1960s. It was formed by three former members of Fairchild Semiconductor, and is thus one of the "Fairchildren". It was acquired in 1966 by Philco-Ford and became their Microelectronics Division. With Frank Wanlass as director of research and engineering, GMe was the first company to design, fabricate, and sell MOS integrated circuits. The first MOS chips were small-scale integrated chips for NASA satellites. In 1964, Wanlass demonstrated a single-chip 16-bit shift register he designed, with an incredible (for the time) 120 transistors on a single chip. That same year, the company entered an agreement to convert a Victor Comptometer tube-based electronic calculator to all-IC form, the Victor 3900, with a planned introduction in early 1966. The task proved to be much more difficult than expected, and GMe was left almost insolvent. The company was purchased by Philco-Ford, at which time Victor gave up on ...

Molecular Beam Epitaxy
Molecular-beam epitaxy (MBE) is an epitaxy method for thin-film deposition of single crystals. MBE is widely used in the manufacture of semiconductor devices, including transistors, and it is considered one of the fundamental tools for the development of nanotechnologies. MBE is used to fabricate diodes and MOSFETs (MOS field-effect transistors) at microwave frequencies, and to manufacture the lasers used to read optical discs (such as CDs and DVDs). History Original ideas of MBE process were first established by Günther. Films he deposited were not epitaxial, but were deposited on glass substrates. With the development of vacuum technology, MBE process was demonstrated by Davey and Pankey who succeeded in growing GaAs epitaxial films on single crystal GaAs substrates using Günther's method. Major subsequent development of MBE films was enabled by J.R. Arthur's investigations of kinetic behavior of growth mechanisms and Alfred Y. Cho's in situ observation of MBE process ...

Dov Frohman
Dov Frohman (Hebrew: דב פרוהמן, also Dov Frohman-Bentchkowsky; born March 28, 1939) is an Israeli electrical engineer and business executive. A former vice president of Intel Corporation, he is the inventor of the erasable programmable read only memory (EPROM) and the founder and first general manager of Intel Israel. He is also the author (with Robert Howard) of ''Leadership the Hard Way'' ( Jossey-Bass, 2008). Biography Dov Frohman was born in March 1939 in Amsterdam, five months before the start of World War II. His parents were Abraham and Feijga Frohman, Polish Jews who had emigrated to the Netherlands in the early 1930s to escape rising anti-Semitism in Poland. In 1942, after the German invasion of the Low Countries and as the Nazi grip on Holland’s Jewish community tightened, his parents decided to give their child to acquaintances in the Dutch resistance who placed him with the Van Tilborghs, an orthodox Christian farming family that lived in the village of S ...

Jean Hoerni
Jean Amédée Hoerni (September 26, 1924 – January 12, 1997) was a Swiss-American engineer. He was a silicon transistor pioneer, and a member of the " traitorous eight". He developed the planar process, an important technology for reliably fabricating and manufacturing semiconductor devices, such as transistors and integrated circuits.

He received his B.S. in Mathematics from the University of Geneva and two Ph.D.s in Physics; one from the University of Geneva and the other from the University of Cambridge. In 1952, he moved to the United States to work at the California Institute of Technology, where he became acquainted with William Shockley, a physicist at Bell Labs who was intimately involved with the creation of the transistor. A few years later, Shockley recruited Hoerni to work with him at the newly founded Shockley Semiconductor Laboratory division of Beckman Instruments in Mountain View, Califo ...

Planar Process
The planar process is a manufacturing process used in the semiconductor industry to build individual components of a transistor, and in turn, connect those transistors together. It is the primary process by which silicon integrated circuit chips are built. The process utilizes the surface passivation and thermal oxidation methods. The planar process was developed at Fairchild Semiconductor in 1959. Overview The key concept is to view a circuit in its two-dimensional projection (a plane), thus allowing the use of photographic processing concepts such as film negatives to mask the projection of light exposed chemicals. This allows the use of a series of exposures on a substrate (silicon) to create silicon oxide (insulators) or doped regions (conductors). Together with the use of metallization, and the concepts of p–n junction isolation and surface passivation, it is possible to create circuits on a single silicon crystal slice (a wafer) from a monocrystalline silicon boule. ...

Dawon Kahng
Dawon Kahng ( ko, 강대원; May 4, 1931 – May 13, 1992) was a Korean-American electrical engineer and inventor, known for his work in solid-state electronics. He is best known for inventing the MOSFET (metal–oxide–semiconductor field-effect transistor, or MOS transistor), along with his colleague Mohamed Atalla, in 1959. Kahng and Atalla developed both the PMOS and NMOS processes for MOSFET semiconductor device fabrication. The MOSFET is the most widely used type of transistor, and the basic element in most modern electronic equipment. Kahng and Atalla later proposed the concept of the MOS integrated circuit, and they did pioneering work on Schottky diodes and nanolayer-base transistors in the early 1960s. Kahng then invented the floating-gate MOSFET (FGMOS) with Simon Min Sze in 1967. Kahng and Sze proposed that FGMOS could be used as floating-gate memory cells for non-volatile memory (NVM) and reprogrammable read-only memory (ROM), which became the basis for EPROM ...

Mohamed Atalla
Mohamed M. Atalla ( ar, محمد عطاالله; August 4, 1924 – December 30, 2009) was an Egyptian-American engineer, physicist, cryptographer, inventor and entrepreneur. He was a semiconductor pioneer who made important contributions to modern electronics. He is best known for inventing the MOSFET (metal–oxide–semiconductor field-effect transistor, or MOS transistor) in 1959 (along with his colleague Dawon Kahng), which along with Atalla's earlier surface passivation and thermal oxidation processes, revolutionized the electronics industry. He is also known as the founder of the data security company Atalla Corporation (now Utimaco Atalla), founded in 1972. He received the Stuart Ballantine Medal (now the Benjamin Franklin Medal in physics) and was inducted into the National Inventors Hall of Fame for his important contributions to semiconductor technology as well as data security.

Semiconductor
A semiconductor is a material which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities (" doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called " metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. Silicon is a critical elem ...
