John Randall (nanotechnologist)
John Neal Randall is an American Electrical Engineer and nanotechnologist. As of 2006, Chief Technical Officer of Zyvex Corporartion. Previously he worked at Texas Instruments from 1985 to 2001, and Lincoln Laboratory (part of the MIT Corporation from 1982 to 1985. He has BS, MS, and Ph.D degrees in Electrical Engineering from the University of Houston.
Additional recommended knowledge
John Randall has been a micro/nano fabricator for approximately 30 years. This could mean that he tells small lies, but actually refers to his research in high resolution patterning for the semiconductor and related industries. In graduate school at the University of Houston he developed e-beam lithography and x-ray lithography. He was attracted to Lincoln Lab, a part of the MIT Corporation by Hank Smith, the inventor of x-ray lithography. There, much to the consternation of Hank Smith, Randall developed Masked Ion Beam Lithography, a technology so obscure, that it gets (as of 2006) only a tangential reference in Wikipedia’s entry on Nanolithography. This lack of notoriety not-with-standing, in 1983, Randall produced 80nm lines and spaces using this masked, short exposure time technique. This resolution is still greater than required for the most advanced (2006) semiconductor devices.
In 1985, Randall fled the frozen wastelands of Massachusetts to return to Texas and work for Texas Instruments where he worked in TI’s Central Research Laboratories on Quantum Resonant Tunneling devices and circuits. Among the world’s first accomplishments (with co-workers Bob Bate, Mark Reed, Alan Seabaugh, Jim Luscombe, Bill Frensley, Gary Frazier, and others) were a quantum dot diode, resonant tunneling transistor, and room temperature quantum tunneling IC. From 1996-1998 Randall was assigned by TI to IMEC in Belgium where he worked on optical proximity correction for IC manufacturing. On his return to Texas, Randall continued to work on advanced optical lithography for IC production.
In 2001, Randall joined Zyvex to become the corporation’s Chief Technical Officer.
