    Abstract: A process for producing regions of high resistivity in gallium arsenide, and other related compounds and mixed crystals which show electrical behavior which is similar to that of gallium arsenide, in which deuterons are implanted into a substrate made of the semi-conductor body with energies up to a maximum value corresponding to a desired depth of penetration into the body. Apparatus for carrying out the process also is described.

    Abstract: A method and apparatus for measuring damage of an ion implanted semiconductor wafer during semiconductor processing. The method includes the steps of conveying the wafer such that a surface of the wafer is substantially parallel to a surface photovoltage electrode of a head assembly during the semiconductor processing and exposing at least a portion of said wafer to light having a wavelength, and an intensity and modulating the light intensity at a predefined frequency. The method also includes the step of varying the frequency of the light intensity modulation and detecting the surface photovoltage in response to light modulated at the various frequencies using the surface photovoltage electrode. The method then calculates an electrical property of the wafer from the photovoltage induced at the surface of the wafer at each of the light intensity modulation frequencies.

    Abstract: A method and apparatus for forming an oxide layer on semiconductors using a combination of ultraviolet rays and heat. The apparatus comprises a chamber having a top surface and a bottom surface and defining a wafer holding cavity; an ultraviolet source at the top surface of said chamber; an infrared source at the bottom surface of the chamber; and an oxygen gas inlet for passing oxygen gas through the chamber. Oxygen gas entering the chamber through the oxygen gas inlet is ionized by ultraviolet rays from the ultraviolet source and reacts with the silicon wafer to create an oxide layer on the silicon wafer in the cavity. Infrared radiation from the infrared source heats the silicon wafer to accelerate the creation of the oxide layer on said silicon wafer.
