In the 1980s, John Schumacher was busy working on a fluidized-bed process to produce polysilicon for semiconductors. Many others were engaged in similar projects as part of a push by the U.S. Dept. of Energy (DOE; Washington DC; www.doe.gov) to develop less-energy-intensive alternatives to the popular Siemens process — a chemical vapor deposition (CVD) technology named for the company that developed it. Most of the projects were abandoned when DOE pulled the plug on the program, and the polysilicon business subsequently fell on hard times because of overcapacity and a slump in semiconductor production.
