IPC: H01S5/022
Filed: 1984-02-03
Abstract: PURPOSE:To form good cleavage surfaces and to facilitate the automation of cleavage by utilizing the thermal strain caused with the increase in temperature at the part of irradiation, by a method wherein scratches extending in the direction of cleavage are irradiated with beam spots of laser light smaller than the resonator length. CONSTITUTION:Scratches M1-Mn extending in the direction of cleavage are made at one side end of the upper surface of a semiconductor laser wafer 11 at intervals of the resonator length of a semiconductor laser diode. Thereafter, a point on a scratch M1 closest to one end of the upper surface of the wafer 11 is irradiated with a laser beam P of pulse form. Irradiation with the laser beam P leads the irradiated part to thermal expansion on heating and then produces strains between the unheated part in the periphery. As a result, the wafer 11 cleaves along the scratch M1. Next, a point on a scratch M2 is irradiated with the laser beam P, and thereafter the scratches M3, M4...Mn are successively irradiated with the laser beam P; thus, the wafer 11 is further cleft along the scratches M3, M4...Mn. A plurality of barform chips 13 obtained thereby are split in the longitudinal direction turning into semiconductor diode chips.
