“Silicon-on-Insulator,” a.k.a. SOI, wafers were originally<br />
manufactured by SiBond, LLC, a joint venture between <strong>MEMC</strong><br />
and IBM. These wafers were produced in 2007.<br />

1983 Ethyl completes $150M<br />
investment to develop granular<br />
polysilicon manufacturing process.<br />
1985 Ethyl completes $70M investment<br />
in granular polysilicon<br />
manufacturing process—PA21.<br />
1987 Ethyl completes startup of PA21<br />
after investing an additional $50M<br />
in the process.<br />
1994 Ethyl spins off chemical business<br />
into a separate publicly traded<br />
company, Albemarle. Polysilicon<br />
manufacturing is part of the new<br />
company.<br />
1995 Albemarle sells PA21 to <strong>MEMC</strong> for<br />
$58M.<br />
1998 <strong>MEMC</strong> completes investment in an<br />
additional silane production unit,<br />
PA22, raising capacity to 2,500<br />
metric tons per year.<br />
2007 <strong>MEMC</strong> completes investment in<br />
third silane production unit, PA23,<br />
raising total capacity to 6,000<br />
metric tons per year.<br />
2008 <strong>MEMC</strong> completes investment in<br />
fourth silane production unit,<br />
PA24; this investment combined<br />
with expansions in Merano raises<br />
total <strong>MEMC</strong> capacity to 8,000<br />
metric tons per year.<br />
In 1994, <strong>MEMC</strong> again partnered with IBM to form<br />
a new company called SiBond, LLC. The company,<br />
based at St. Peters, used technology developed by<br />
the IBM Research Division plus manufacturing<br />
and sales techniques developed by <strong>MEMC</strong> in the<br />
creation of a specialty technology called “siliconon-insulator”<br />
(SOI) technology to be used for<br />
memory devices containing more than one gigabit<br />
of data.<br />
The specialty wafer’s makeup is a sort of sandwich
