Abstract

PURPOSE:To prevent the scattering of a laser light from a semiconductor laser element by so forming a substrate that the pressing force for cleavage thereof not may be applied vertically to the P-N junction surface and thus eliminating strain at the P-N junction surface. CONSTITUTION:A crystalline layer of P type PbS1-xSex is diffused on the surface layer of the subsrate of N type Pb S1-x Sex. Thereafter, gold is evaporated as film for electrode on the surface and bottom of the substrate. Subsequently, cutting edge of a razer or the like is brought into contact with the surface of the substrate to cleavage the substrate into shapes of slender rectangles. Then, the cutting edge 11 of the razer is brought into contact with the position mostly isolated from the P-N junction surface 1 formed on the substrate to cleavage the substrate, and a chip of stereoscopic shape is formed for forming the laser element.
