When the buried oxidizing film 4 is moved by application of the electric field, silicon of amorphism appears on an interface disposed behind the direction of this movement, and if a system is at a sufficiently high temperature, this silicon is recrystallized with an adjacent single-crystal silicon layer used as a seed. When an electric field reverse to that in the amorphism process is applied further, a buried depth of the buried oxidizing film 4 is enlarged and silicon layers appearing behind the direction of this movement are serially recrystallized. Hence, crystallinity of the surface silicon layer 5 can be obtained and also good electrical characteristics can be obtained on the interface between the silicon layer 5 and the buried oxidizing film 4.
