Borror, Dan (Daniel)

Biographical Notes

Daniel (Dan) Borror earned a B.A. in mathematics and chemistry from San Jose State University. He joined Fairchild circa 1961 where he performed experiments on the electrochemical anodization of silicon. He worked at MOS pioneer General Microelectronics in the mid-1960s and was a co-founder of the mask-making firm Cartesian in 1969. Cartesian was also one of the first companies to offer MOS foundry services. Cartesian made the masks and fabricated wafers for the AL-1 8-bit microprocessor slice designed by Lee Boysel for Four-Phase Systems in 1969. He worked at Toshiba America for five years as the Director of VLSI Design Engineering, provided technical training at Apple (1985–1990), technical writing at AMCC (1998-2003) and consulted for networking companies.
