Low Temperature Process for Producing Indium-Containing Semiconductor Materials.

Authors: Robert W. Gedridge Jr; DEPARTMENT OF THE NAVY WASHINGTON DC
Abstract:
Chemical vapor deposition process for producing indium-containing semiconductor materials, particularly III/V indium-containing semiconductor materials, using triisopropylindium as the source of indium. In the process a flow of triisopropylindium and a flow of a group V source or precursor, e.g. AsH3, are directed into a reactor in contact with a heated substrate. The triisopropylindium and group V precursor are at least partially decomposed, depositing by chemical vapor deposition an indium-containing III/V semiconductor material on the substrate. The result is lower pyrolysis temperatures and less carbon impurity incorporation into the indium-containing semiconductor material than when commercially available indium sources are used.
