Title: Manufacture of semiconductor laser
Inventor: KISHI TADAHIKO
IPC: H01S5/00
Filed: 1994-01-28
Abstract: PURPOSE:To obtain a semiconductor laser which is improved in characteristic temperature and can stably operate at a high temperature by successively growing prescribed layers, a p-type clad layer, a p-type hetero-buffer layer, and a ca[ layer composed of a compound containing no P on an n-type GaAs substrate. CONSTITUTION:After successively growing an n-type GaAs buffer layer 2, n-type (AlxGa1-x)0.5In0.5P clad layer (0<x<=1) 3, Ga0.5In0.5P active layer 4, p-type (AlxGa1-x)0.5In0.5P clad layer (0<x<=1) 5, and p-type Ga0.5In0.5P hetero-buffer layer 6 on an n-type GaAs substrate l by using Zn as a dopant, a cap layer 7 is successively grown on the layer 7 in the course of the first growing process. The layer 7 is composed of a compound containing no P so as to eliminate the need of a PH3 atmosphere at the time of post-growth cleaning. Therefore, the carrier concentration in the p-type clad layer can be increased, because the activity of the p-type dopant in the layer is improved, and, at the same time, the diffusion of the p-type dopant to lower layers can be reduced.

Abstract: PURPOSE:To perform paint-out processing of a closed area at a high speed by applying a sequential painting-out method where the right and left ends of the closed area are searched and painted out via a line including a start point and the right ends of the lines above and under the painted-out line are searched and stacked. CONSTITUTION:A closed area GAMMA enclosed by boundary lines alpha and beta is given to a controller of a closed area painting-out device and stored in a memory. The controller defines a given point Ps of the area GAMMA as a start point and searches a right end point Xr where (x+1, y) is equal to a point on a boundary line and a left end Xl where (x-1, y) is equal to a point on a boundary line. Thus the controller produces a line painting-out picture to paint out the part between the points Xr and Xl and outputs this picture to a printer. Then a point Xr on the line higher than said painted out line by a step is defined as a start point and a right end point UXr is searched for stacking and painting-out of a line. Such operations are successively repeated so that a closed area is painted out at a high speed.
