Title: Dicing method of semiconductor
Inventor: NAKAJIMA MASAHIDE
IPC: H01L21/78
Filed: 1987-09-28
Abstract: PURPOSE:To improve reliability by preventing a crack at an end part of a pellet and progress of the crack or a flaw in a process after that, by a method wherein cutting is performed to a predetermined depth of the surface of a wafer in a vertical direction of the same by performing registration to a V-shaped groove part by using a diamond blade and a cut sectional form is made of Y-shaped type. CONSTITUTION:A V-shaped groove is formed by cutting the central part of a dicing sphere 2 deeply into a predetermined depth with a diamond blade 5 having an arbitrary angle (45-120 deg.) at the tip. As an angle of a crack of an end part of a pellet is determined by kind of a crystal and oventation, a tip angle of the diamond blade 5 is decided in conformity with them. Then cutting is performed deeply into the predetermined depth by registering to the center of the V-shaped groove by using a thin diamond blade 6. A depth of the groove to be formed with the blade 5 is set up so that width 7 of the upper part of the V-shaped groove becomes narrower than a width of the dicing sphere 2 and wider than a notched width 8 to be obtained by cutting with the blade 6. A cut sectional form obtained by rounding off only a surface part of the pellet can be made a Y-shaped type by performing dicing like this.

Title: Semiconductor laser
Inventor: MUSHIGAMI MASAHITO
IPC: H01S5/16
Filed: 1984-11-19
Abstract: PURPOSE:To reduce optical damage of a laser resonator at its maximum output by a method wherein a stripe-geometry groove, shorter than the laser resonator wavelength and as deep as to reach a first upper clad layer, is provided in a current limiting layer along a direction orthogonally meeting the direction of cleavage. CONSTITUTION:A current limiting layer 23 is constituted of alight absorbing layer 23a made of N-type GaAs and evaporation stopping layer 23b made of N-type AlxGa1-xAs. A stripe-geometry groove 30 is provided, shorter than the laser resonator wavelength and as deep as to reach a first upper clad layer 22, along a direction orthogonally meeting the direction of cleavage. Every one of the layers to be formed on the current limiting layer 23 is also provided with a stripe depressed corresponding to the geometry of the current limiting layer 23. This design allows the difference to be smaller between the refraction indexes at both ends (faces of cleavage la, lb), respectively, of the laser resona tor. Laser spreads to reach as far as a first upper clad layer, which results in a lowered end face optical density, this contributing to the realization of a laser resonator suffering from less optical damage at the maximum output.

Filed: 1992-08-21
Abstract: PURPOSE:To improve breaking performance while eliminating imbalance in distributed flows, and dispense with special process control by inserting resistors to correct imbalance in resistance values of both fuses on contact surfaces between one clip and a connecting conductor. CONSTITUTION:Both end pieces 3 of respective clips 2 of both respective electric current fuses 1 are superposed upon both surfaces of both end parts of a connecting conductor 9, and are fastened to each other by means of bolts and nuts. Resistors 10 to correct imbalance in resistance values of both the fuses 1 are inserted on contact surfaces between one clip 1 and the connecting conductor 9, and are corrected so that resistance values of distributed circuits by both the fuses 1 in an electric current supply passage become equal to each other. Thereby, since the resistance values of the distributed circuits of both the fuses 1 connected in parallel to each other become equal to each other, imbalance in distributed flows can be eliminated, so that breaking performance can be improved. Since special process control to restrain dispersion of the resistance values of both the fuses 1 can be dispensed with, a cost increase can be prevented.
