Abstract
Disclosed herein is a method of forming a single-crystalline thin film having excellent crystallinity on a base material without depending on the material for and crystallinity of the base material. In this method, a base material is provided thereon with a mask which can prevent chemical species contained in a vapor phase from adhering to the base material. The base material is continuously moved along arrow A, to deliver a portion covered with the mask into the vapor phase for crystal growth. Thus, a thin film is successively deposited on the portion of the base material, which is delivered from under the mask, from the vapor phase. A crystal growth end is formed on a boundary region between a portion of the base material which is covered with the mask and that which is exposed to the vapor phase, so that a crystal having the same orientation as the growth end is grown on a portion of the base material newly exposed by the movement.
