Abstract:
A method of batch processing semiconductor substrates in a process for making semiconductor lasers, the semiconductor lasers being formed from laser bars that are cleaved from a laser cell, each of the laser bars having oppositely facing side surfaces, the method comprising the steps of:providing in a vacuum chamber a laser cell and a cassette capable of receiving and holding a plurality of laser bars; creating a desired vacuum level within the vacuum chamber; performing a cleaving operation that comprises cleaving a laser bar from the laser cell and loading the cleaved laser bar into the cassette, said cleaving operation being repeated until at least a plurality of laser bars are cleaved off the laser cell and loaded into the cassette; and depositing a layer of material simultaneously on one side surface of a plurality of the laser bars while positioned in the cassette.
