Patent number: 12062544Abstract: A laser annealing method for a semiconductor device, includes: a first step of adding an impurity to a semiconductor substrate; and a second step of irradiating a region to which the impurity is added with a pulsed laser beam a plurality of times to anneal the semiconductor substrate. In the second step, a first region of a portion of the region to which the impurity is added is irradiated with the pulsed laser beam, and after a predetermined time interval, a second region adjacent to the first region is irradiated with the pulsed laser beam. The predetermined time interval is larger than a pulse interval of the pulsed laser beam.Type: GrantFiled: December 21, 2020Date of Patent: August 13, 2024Assignees: SUMITOMO HEAVY INDUSTRIES, LTD., FUJI ELECTRIC CO., LTD.Inventors: Takeshi Aiba, Hiroshi Takishita, Takashi Yoshimura
