Abstract
PURPOSE:To passivate the surface of the compound semiconductor by irradiating a light having an opaque wavelength for the semiconductor in an intensity of 0.5- 1kw/cm<2> on the surface of the semiconductor. CONSTITUTION:An Ar laser light (having a wavelength of 5,149Angstrom ) is condensed through a lens to provide an intensity of 0.5-1kw/cm<2>, and the condensed laser light is irradiated on the light resonant surface of a laser diode having a double hetero junction of A GaAs-GaAs series. If the intensity of the laser light is lower than the prescribed range, no effect can be obtained, while if the intensity is higher than the prescribed range, the surface of a specimen is damaged. If the laser light is irradiated for shorter than one minute, no effect can be obtained. With such a treatment a stable oxide film is formed on the surface of a light resonator, and the surface of the resonator is annealed by a light absorption to be stabilized. In such a configuration the surface of the compound semiconductor can be simply passivated, and the reliability of the compound semiconductor can be consequently improved.
