Patent JP-S6453411-A (JP)
Title: Manufacture of semiconductor thin film
Inventor: OKAMOTO AKIHIKO
IPC: H01L21/203
Filed: 1988-04-28
Abstract: PURPOSE:To selectively form a III-V compound semiconductor on a substrate, by a method wherein, a group III single unit raw material is heated up and evaporated in a vacuum atmosphere, and when a III-V compound semiconductor is formed by feeding a group V raw material, the pressure of vapor of said group III single unit raw material on the substrate is controlled. CONSTITUTION:When a molecular beam epitaxial growth method is conducted using a solid- state raw material, group V raw material is supplied excessively, and the growing speed is controlled by the feeding quantity of the group III. When the partial pressure of the group III atoms to be supplied is set at P, and the pressure of the group III atoms in a thermal equilibrium state on the heated substrate is set at Peq., the crystal growth speed is proportioned to P-Peq. When substrate temperature is set so that the crystal growth speed becomes sufficiently small Peq. When compared with the P in ordinary molecular beam epitaxial growth, the crystal growth speed becomes P, in other words, the speed is proportioned to the partial pressure of the group III atoms to be supplied. However, when the Peq. is larger than the P, no crystal growth is generated. Accordingly, the substrate temperature, the partial pressure of the group III atoms, the partial pressure of the group V atoms are selected so as to have the P-Peq. of positive, and the P-Peq. becomes negative on the thin film 2, aud the compound semiconductor 3 is selectively formed on the substrate.
