Patent GB-2302209-A (GB)
Title: Method of growing compound semiconductor layer
Inventor: KIZUKI HIROTAKA
IPC: H01L21/20
Filed: 1995-12-15
Abstract: A method of growing a compound semiconductor layer includes growing a compound semiconductor layer (12) on a front surface of a semiconductor substrate (11). The layer is grown so that a lattice arrangement direction of the semiconductor layer in a plane parallel to a -100  plane is inclined by a prescribed angle with respect to a lattice arrangement direction of the semiconductor substrate in a plane parallel to the -100  plane. Thus some atoms constituting crystal lattices of the compound semiconductor layer (12) match with some atoms constituting crystal lattices of the semiconductor substrate (11) periodically. The layer is grown by MOCVD, MBE, GSMBE, CBE, VPE or ALE and may be used in a laser.
