Title: Manufacture of semiconductor memory
Inventor: NOGUCHI TAKASHI
IPC: H01L27/04
Filed: 1988-10-24
Abstract: PURPOSE:To execute a heat treatment used to stabilize a polycrystalline silicon film without causing a temperature rise at a surface part of a semiconductor substrate by a method wherein the polycrystalline silicon film is irradiated with a pulsed laser beam and is heated. CONSTITUTION:A polycrystalline silicon film 9 is irradiated with a pulsed laser beam by an excimer laser (XeCI); it is activated. Since the polycrystalline silicon film 9 has an absorption coefficient of nearly 100% with reference to ultraviolet rays and has a film thickness of about 50 to 800Angstrom , the pulsed laser beam radiated from the laser is absorbed completely by the polycrystalline silicon film 9. Accordingly, the lesser beam does not reach the substratum side of the polycrystalline silicon film 9; a semiconductor substrate is hardly heated. Thereby, the polycrystalline silicon film can be heated effectively without causing a temperature rise of the semiconductor substrate; a film quality to realize a high resistance and to stabilize a resistance can be controlled.

Title: Formation of low reflectivity edge face of optical element
Inventor: GOTO KATSUHIKO
IPC: H01S5/00
Filed: 1987-10-22
Abstract: PURPOSE:To improve reliability, by epitaxially growing a lower clad layer, an active layer and an upper clad layer on a substrate, in which a deep groove is formed by etching, cleaving the device at the center of the groove in parallel with the groove, and isolating elements. CONSTITUTION:A groove 5 is formed in a semiconductor substrate 1 by etching. Thereafter, at least a lower clad layer 2, an active layer 3 and an upper clad layer 4 are epitaxially grown sequentially on the semiconductor substrate 1. The device is cleaved at the center of the groove 5 in parallel with the groove, and elements are isolated. Therefore the surface of an epitaxial layer 6 is inclined at the end surface of the extended flat part of the active layer 3. Thus a very low reflectivity is obtained. Since the vicinity of the edge face becomes a window structure, deterioration of the edge face due to the absorption of light is hard to occur. In this way, a highly reliable optical element can be obtained.
