Title: Semiconductor device
Inventor: YAMAGUCHI KOJI
IPC: H01L29/205
Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To solve the problem that, when a hetero interface is formed between materials having different lattice constants or large physical properties, various kinds of defects typified by the misfit dislocation, lattice vacancy, etc., are formed in the interface and the sheet resistivity is raised by electron scattering, resulting in the sensitivity drop and deterioration in characteristics of a Hall element. SOLUTION: In a semiconductor device, a conductive layer 12 composed of undoped InAs grown by the MBE method is provided on an insulating semiconductor substrate 11 composed of a GaAs crystal, and ohmic electrodes 13 and 14 which are used for injecting an electric current into the conductive layer 12 are provided on the layer 12. A cavity 15 is formed by selectively etching the GaAs crystal of the substrate 11 from the lateral direction in the interface between the conductive layer 12 and the substrate 11, in which misfit transitions exist at a high density due to the difference in lattice constant between the InAs and GaAs.  Consequently, after the GaAs crystal occupying part of the underlying portion of the hetero junction is removed, the misfit transitions disappear and a conductivity improvement corresponding to an electrical resistance of several times lower than the previous resistance is obtained.
