product manufactured and sold by ADCS was tetraethylorthosilicate
(TEOS), which is used as an insulating and conducting material on
semiconductor computer chip wafers.
In 1988, Siegele started up ADCS with an initial
capitalization of $150,000. Initially, ADCS maintained its small
laboratory and manufacturing plant in Amherst, Wisconsin, and its
sales office in Siegele’s apartment in San Jose, California.
Beginning with its first year of operation, ADCS was successful
and profitable.
In 1990, with a $72,000 10-year commercial bank loan which
it had obtained, ADCS purchased approximately 1.8 acres of land
in Burnet, Texas, on which ADCS constructed a new 3,000- to
4,000-square-foot manufacturing plant into which ADCS relocated
its laboratory and manufacturing plant that had been located in
Amherst, Wisconsin. The $72,000 bank loan was paid off in 1993.
In the early 1990s, ADCS developed and began manufacturing
stainless steel canisters that allowed for safe handling and
processing of TEOS and of other chemicals used in the computer
industry.
In the mid-1990s, ADCS developed and patented, and then
began manufacturing and selling, a dual canister chemical
refilling system that allowed TEOS and other chemicals to be
continuously applied to computer chip wafers through a processing
tool without interrupting the chip manufacturing process while
