Title: Semiconductor device
Inventor: MIZUTANI HIDEMASA
IPC: H01L21/337
Filed: 1987-12-06
Abstract: PURPOSE:To produce a single crystal or a polycrystalline crystal with ease and at low cost by a method wherein a semiconductor crystal is grown out of a seed crystal arranged on a substrate, the resultant crystal consists of a plurality of semiconductor layers different in conductivity type, the conductivity type varies along the direction of radius, and the semiconductor layers are exposed on the substrate surface. CONSTITUTION:A seed single crystal 2 is placed on an SiO2 film 1. A selective Si epitaxial growth process is accomplished on the seed single crystal 2. At the initial stage of the growth, an n-type doping gas is used, when a p-type Si single crystal 4 is epitaxially grown direct on an n-type Si single crystal 3. When the p-type Si single crystal 4 has become as thick as specified, the n-type doping gas is replaced by a p-type doping gas, for the epitaxial formation of an n-type Si single crystal 5 on the ptype Si single crystal 4. The result is an island-geometry Si single crystal built of a p-n-p laminate with its component layers formed epitaxially. The island is reduced in height to an appropriate level and the thus-created surface is flattened. A circular cone results, with its top removed, built of an n-type Si single crystal 3 covered by a p-type Si single crystal 4 further covered by an n-type Si single crystal 5.
