Patent JP-S61196592-A (JP)
Title: Manufacture of composite resonator type semiconductor laser device
Inventor: TOKUDA YASUKI
IPC: H01S5/0625
Filed: 1985-02-26
Abstract: PURPOSE:To enable the title laser device to be easily produced with high precision by means of crystal growth on a flat surface without utilizing cleavage, by constructing at least a part of an optical waveguide in a superlattice structure or quantum well structure, converting a part of this superlattice structure or quantum well structure into mix crystal, and forming two or more laser sections having different resonator lengths. CONSTITUTION:A second clad layer of P-type AlGaAs 6 and an active layer 9 of a multiple quantum well structure are produced successively on a P-type GaAs substrate 7 by the molecular beam epitaxy. A masking material of silicon nitride is provided thereon and a part of the mask 11 is removed by etching to make a mask pattern. The substrate with the mask pattern is encapsulated together with ZnAs2 and annealed at a temperature of several hundred degrees so as to diffuse Zn in the portion not covered with the mask. Thus, the diffused portion penetrates the multiple quantum well structure to convert it into mix crystal. The mask 11 is then removed and a first clad layer of N-type AlGaAs 4 and an N-type GaAs cap layer 3 are successively produced on the flat surface of the active layer 9 by the molecular beam epitaxy. Current stopping layers 2 of SiO2 are provided transversely at both ends by the CVD process, and a first electrode 1 and a second electrode 8 are vapor-deposited.

Title: Crystal growth device
Inventor: OISHI YOSHIRO
IPC: H01L21/26
Filed: 1986-02-24
Abstract: PURPOSE:To form hetero-junction and superlattice structure easily by dividing a growth chamber into the plural and moving a substrate for crystal growth in growth spaces in which molecular beams are separated at every epitaxial growth. CONSTITUTION:A substrate 22 for crystal growth is mounted to a shifter 21, a shutter 20 is opened positioned in a first chamber, an InAlAs crystal is grown in an epitaxial manner by a material in the first chamber, and the substrate 22 for crystal growth is moved into a second chamber by the shifter 21 and the InGaAs crystal is grown. Consequently, the introduction period of the substrate 22 for crystal growth to the first chamber and the second chamber is controlled alternately by using the shifter 21, thus easily growing a desired superlattice. Since the temperature of an evaporation source does not change with the opening and closing of the shutter 20 at that time, molecular beams do not fluctuate, thus keeping the mol ratio of In and Ga constant at all times according to a design value.

Title: Back-up device for numerical value calculation
Inventor: KIZAWA MAKOTO
IPC: G06F17/50
Filed: 1989-02-22
Abstract: PURPOSE:To reduce an error of calculation due to a fact that the form of a boundary of an object is not accurately shown by obtaining a solid angle based on a point near a boundary, calculating a relative deviation between the obtained solid angle and a solid angle to a circle having its set radius equal to a radius around the foot of a perpendicular, ad fractionating a mesh according to the value of the relative deviation. CONSTITUTION:The length l of a reference radius is set for evaluation of a solid angle. At the same time, a foot 15 of a perpendicular line to a boundary is obtained from a point where the mesh fractionation is evaluated to obtain a contour distant from the boundary by the reference length around the foot 15. Then a solid angle deltaOMEGA is obtained to the contour from the evaluating point for mesh fractionation. Furthermore a flat circle having a reference radius is drawn around the foot 15 and the solid angle OMEGA of the circle is obtained. Then the relative deviation is obtained between both solid angles. When the relative deviation is smaller than the reference value delta for mesh fractionation together with a fixed distance set from the boundary and near a mesh boundary, the mesh is fractionated. Thus the cross section data is obtained for a highly accurate and fine solution.
