Abstract : The effects of furnace temperature, time, water temperature, and flow rate upon oxidation thickness were studies. The effect of these parameters upon diode characteristics was also investigated. A K + S Model 447 nailhead bonder was adopted for use with the Ultrasonic Welder. Devices were fabricated with the new setup. New masks providing for internal shorting of the grids were received. Devices were sucessfully fabricated using this technique. A final design for the mesa etching fixture was fabricated. (Author)
