Latest Patents

Wakabayashi's latest patents include a laser annealing method and a laser annealing device. The laser annealing method involves preparing an annealing object where an absorbing film made of metal is formed on the surface of a silicon carbide wafer. This wafer contains an unactivated dopant that is activated by directing a laser beam onto the absorbing film. The power density of the laser beam is carefully controlled to induce a silicide reaction between the absorbing film and the wafer, resulting in the evaporation of a metal silicide film. The laser annealing apparatus is designed to hold the annealing object in a position where a laser beam from a laser light source can be incident. An infrared detector is employed to detect heat radiation from the annealing object, and an optical element is placed in the pathway of the heat radiation to ensure that only appropriate wavelengths reach the detector.
