Title: Semiconductor element
Inventor: BITO YOSHIFUMI
IPC: H01L21/205
Filed: 1988-12-28
Abstract: PURPOSE:To suppress through dislocation in hetero structure so as to improve quality by laminating alternately plural intermediate layers, which are formed respectively from compound semiconductor crystals whose thermal expansion coefficients are different from each other, between an Si substrate and a III-V compound semiconductor layer. CONSTITUTION:Plural intermediate layers 28-31 are laminated on an Si substrate 3, and III-V compound semiconductor layer 27 is formed thereon. These intermediate layers 28-31 are formed of compound semiconductor crystals whose thermal expansion coefficients are different from each other. Accordingly, even in the case that the dislocation exist at the interface between the Si substrate 3 and the intermediate layer 28, the interface between each intermediate layer 28-31, and the interface between the intermediate layer 31 and the III-V compound semiconductor layer 27, thermal stress based on the difference of thermal expansion coefficient arises between the intermediate layers, and by this thermal stress the dislocation at the same interface shift reciprocally, unite, and disappear. Hereby, the crystallizability of a semiconductor element, that is, etch pit density can be reduced, and the surface property of the obtained semiconductor element can also be smoothed.
