Title: Formation of single crystal thin film
Inventor: UEYAMA SUMIYOSHI
IPC: C30B29/06
Filed: 1995-01-26
Abstract: PURPOSE: To easily form a single crystal thin film on an arbitrary substrate. CONSTITUTION: SiH4 is supplied while an SiO2 substrate 31 is held at about 600 deg.C, by which CVD is executed and Si is deposited on the SiO2 substrate 31. At this time, the Si is deposited as axially oriented polycrystals aligned in the <110> direction to a direction perpendicular to the surface of the SiO2 substrate 31. Simultaneously, a beam of Ne is cast to the surface of the Si under deposition at an incident angle of 35 deg. with the direction perpendicular to the surface of the SiO2 substrate 31. Consequently, the rearrangement of the Si atoms arises in such a manner as to direct the <111> direction which is the direction perpendicular to the closed packing surface toward the beam. The thin film 33 of the single crystal Si is, therefore, formed atop the SiO2 substrate 31. As a result, the single crystal thin film is obtd. by the easy method of merely applying the irradiation with the beam under the same conditions as the conditions at the time of forming the axially oriented polycrystal thin film.
