Abstract:
A process for the formation of a cap layer for semiconductors comprising:disposing a semiconductor in a gas containing nitrogen atom as a component element; conducting instantaneous heat treatment for a surface of said semiconductor thereby to introduce the nitrogen atom contained in said gas into a surface of a semiconductor; wherein the surface of said semiconductor is instantaneously heated, and then cooled instantaneously, whereby a temperature in said surface of the semiconductor is maintained at a low temperature, and said instantaneous heat treatment is executed by irradiating pulse laser beam having a frequency and a fluence onto the surface of said semiconductor with a pulse number; combining a component element of said semiconductor in the vicinity of the surface of said semiconductor into which the nitrogen atom contained in said gas has been introduced with the nitrogen atom contained in said gas to form a nitride compound being a compound of said component element of the semiconductor and the nitrogen atom contained in said gas on the surface of said semiconductor; and utilizing said nitride compound as a cap layer for the surface of said semiconductor.
