Title: Compound semiconductor substrate and its manufacturing method
Inventor: MORIYA AKIHIRO
IPC: H01L27/00
Filed: 1994-03-03
Abstract: PURPOSE:To prevent the conductivity of silicon substrate from affecting a compound semiconductor on it by allowing a compound semiconductor layer to be subjected to epitaxial growth on SOI substrate where the thickness of an upper silicon layer is specified. CONSTITUTION:An upper silicon layer 4 should be as thick as approximately 50-1000Angstrom . The practical depletion layer thickness can be determined by the amount of total space charge (impurity concentration) and surface potential. By extremely making thin the upper 5 silicon layer, lattice distance is extended as compared with that of silicon single crystal and as a result the lattice mismatching with GaAs layer 5 which is subjected to epitaxial growth on it can be eased since oxygen atom enters between silicon lattices on the upper silicon layer 4. Therefore, the GaAs layer 5 which is subjected to epitaxial growth becomes a compound semiconductor layer with less dislocation defect.
