ENDICOTT, N.Y. -- A novel process-monitoring and -control system has produced excellent semiconductor laser wafer yields, according to the president of a company that has licensed the technology from the US government. Semiconductor Laser International Corp. President Geoffrey Burnham said the desorption mass spectrometry technology it licensed from the US Air Force Wright Laboratories has enabled the firm to produce CW laser devices with wafer manufacturing yields of around 40 percent. Burnham said that while wafer yields in silicon are about 80 percent, typical commercial-scale...Read full article
