Title: Manufacture of semiconductor device
Inventor: MIYAO MASANOBU
IPC: H01L21/268
Filed: 1979-10-01
Abstract: PURPOSE:To elevate the efficiency of annealing of a semiconductor device by a method wherein a laser beam is irradiated to a semiconductor substrate being ion implanted through a newly formed thickness of film or another kind of insulating film. CONSTITUTION:A P type substrate 1 is oxidized to form oxidized layers 2 having the 500Angstrom  thickness on the both main faces, As ions are implanted through the oxidized film to form an implanted region 4. After an SiO2 film 5 having 700Angstrom  thickness is formed on one side main face by the CVD method, a ruby laser beam 6 is irradiated to it to anneal the impurity implanted region 4. Accordingly, because the insulaing films having respectively the most suitable thickness for ion implantation and laser irradiation can be used, respective efficiency is improved. Especially the efficiency of annealing by laser beam becomes maximum when the thickness of the insulating film is lambda/4n, (lambda: wave length of incident beam, n: refractive index of insulating film).

Abstract: PURPOSE:To obtain a semiconductor laser with quantum well structure to oscillate at wavelength detectable having sufficient detection efficiency even with a photo diode of the same composition by a method wherein the active layer of the laser device is made to have a quantum well structure, and loss generated inside of a resonator is made larger than the optical gain of the active layer generated according to transition between first quantum levels. CONSTITUTION:A groove 103 is etched vertically according to reactive ion beam etching, and forms the surface of the resonator on one side of a quantum well structural semiconductor laser 1. Length of the resonator of the quantum well structural semiconductor laser 1 is 400mum, while protons are implanted to the part of length 50mum out of length of the resonator. No current is injected to the proton implanted part 16 thereof, while light is absorbed thereto. Therefore loss generated inside of the resonator is enlarged larger than the optical gain between first quantum levels, and the quantum well structural semiconductor laser oscillates at short wavelength. Accordingly, the quantum well structural semiconductor laser 1 oscillates at wavelength detectable having sufficient efficiency with a photo diode 2 for monitoring of the same composition.
