Title: Inspecting device for semiconductor laser chip
Inventor: MOTOMURA SHINJI
IPC: G01M11/00
Filed: 1987-07-18
Abstract: PURPOSE:To prevent a semiconductor laser chip from staying on a measurement electrode by injecting gas from an injection opening for the gas to the surface of a semiconductor laser chip. CONSTITUTION:The injection opening 8 for the gas is provided to the measurement electrode 4 and when a suction collect 2 moves up after measurement, the gas is injected from the injection opening 8 to the surface of the semiconductor chip 1 to force the semiconductor laser chip 1 to leave the measurement electrode 4. Consequently, the adhesion of the laser chip 1 to the electrode 4 is broken by the injection of the gas from the electrode 4, e.g. nitrogen and the laser chip is separated from the electrode 4 and therefore prevented from staying on the electrode 4.
