Abstract
A thin film of a metal of which eutectic or compound is produced together with a semiconductor which is to be grown in its crystalline form is deposited on an amorphous (quartz glass) substrate. The thin film is patterned with a periodic pattern of a polygon having cross angles of multiples of about 60.degree., then the resulting substrate is heated at a temperature higher than the eutectic temperature of the metal and the semiconductor, and the semiconductor is deposited on the thin film under such heating condition, so that a crystalline film of the semiconductor is precipitated on the substrate. Such crystalline film is grown on a planar substrate at a low temperature of about eutectic temperature.
