    摘要: A semiconductor device in which an insulating layer having a window is formed on a semiconductor substrate, a semiconductor layer is formed on the insulating layer and a semiconductor element is formed on the semiconductor layer, has the advantages of high-speed operation and low power consumption. A conventional manufacturing method involves a high-temperature, time-consuming step by which the semiconductor layer for forming thereon the semiconductor element is formed so that it may have a proper impurity concentration. In the present invention, however, a portion of the semiconductor layer and a portion of the underlying substrate are rendered molten by annealing with an energy beam as of a laser, by which an impurity contained in the substrate is diffused into the semiconductor layer. Accordingly, no high-temperature, time-consuming step is involved in the present invention, permitting the production of a semiconductor device of excellent characteristics.
