Title: Heteroepitaxial film
Inventor: OBE ISAO
IPC: H01L21/205
Filed: 1988-02-05
Abstract: PURPOSE:To improve the service life of the subject film, by forming a second single crystal layer of different material on a single crystal substrate by epitaxial growth, and therein doping dislocation control atoms, the number of atoms roughly corresponding to the number of dislocations, to control proliferation or migration of dislocations generated in the second single crystal layer. CONSTITUTION:In the hetero epitaxy wherein, on a first single crystal substrate, a second single crystal layer of different material is formed by epitaxial growth, dislocation control atom to control proliferation or migration of dislocation generated in the second single crystal layer is doped in the second single crystal layer, the number of atoms almost corresponding to the number of dislocations. In the case where active elements are built in a heteroepitaxial film and operated, the stress due to external causes such as temperature, voltage and current is applied to the heteroepitaxial film, and the dislocation tends to the proliferation or the migration. However, since the doped atom fixes the dislocation, the proliferation and the migration of dislocation are restrained. Thereby, the service life of active elements is remarkably improved.
