    • PROBLEM TO BE SOLVED: To form a film of a superconductive material on a sapphire substrate having a film thickness of ≥300 nm by suppressing generation of a microcrack, and to provide a method for producing the same.SOLUTION: In this method for producing an oxide superconductive material, a superconductive thin film material which is epitaxially grown on a substrate is produced through: a step (1) of applying an organic compound solution of a metal whose oxide forms a superconductive material onto a substrate so as to be dried; a laser irradiation step (2) of photolyzing an organic component in the organic compound of the metal by an excimer laser which is ultraviolet light; a temporary calcining step (3) of thermally decomposing the organic component in the organic compound of the metal; and a glost firing step (4) of performing conversion into a superconductive material. In the method, before performing the glost firing step, laser irradiation is performed only to a predetermined spot to intermingle an a-axially grown precursor spot with a c-axially grown precursor spot in the superconductive material, and then the glost firing step is performed, and thus only the predetermined spot is c-axially grown, to thereby alleviate internal stress of the superconductive material.

    • PROBLEM TO BE SOLVED: To effectively activate impurities of a semiconductor substrate without roughening its surface in activating the impurities.
      SOLUTION: A harmonic laser beam having a wavelength of ≤390 nm is emitted onto an impurity-containing surface layer of a semiconductor substrate to activate the impurity. By the use of a laser beam with an absorption coefficient larger than a light absorption coefficient of a laser beam with a wavelength of 400 to 650 nm, the surface of the semiconductor substrate can be heated concentratedly, so that the impurity doped in an area shallower than 100 nm in the semiconductor substrate can be activated efficiently. By the use of a solid-state laser oscillator emitting a laser beam with a wavelength of ≤390 nm, a laser beam with a wavelength in an ultraviolet region similar to that of an excimer laser can be emitted at a repeating frequency as high as 6-12 kHz which is unique to a solid-state laser, with high pulse-to-pulse stability. Semiconductor substrates having stable quality can thereby be manufactured with high throughput.
