    摘要: A method of selectively heating a predetermined region of a semiconductor substrate includes providing a semiconductor substrate, selectively focusing a free carrier generation light on only a predetermined region of the semiconductor substrate, irradiating the free carrier generation light on the predetermined region of the semiconductor substrate to increase a free carrier concentration within the predetermined region of the semiconductor substrate, wherein the free carrier generation light causes the predetermined region to increase in temperature by less than a temperature necessary to change the solid phase of the predetermined region, and irradiating the semiconductor substrate with a heating light to selectively heat the predetermined region of the semiconductor substrate.
