Title: Manufacture of semiconductor thin film
Inventor: TAKAHASHI JUNICHI
IPC: H01L21/263
Filed: 1988-04-04
Abstract: PURPOSE:To enable heating temperature of substrate on forming a thin film to be low and improved interface characteristics to be obtained by directing synchrotron radiation light to the surface of substrate semiconductor to allow photolysis of gas molecule and excitation of surface adsorption molecule to take place. CONSTITUTION:After a chemical compound gas including a semiconductor element which is an original material and a chemical compound gas including an impurities element are subject to thermal decomposition by a gas cracking cell 3, it is directed to a semiconductor single-crystal substrate 5 heated to an optimum temperature by a heater 4 for heating substrate. At the same time, synchrotron radiation light is allowed to enter from a synchrotron radiation light introduction port 2 and is directed vertically to the semiconductor single- crystal substrate 5. Thus, gas molecule reaching near the surface is subject to photolysis and the adsorption probability becomes even higher or the reaction of gas molecule adhered to the surface of substrate is accelerated. It allows heating temperature of substrate on forming a thin film to be low and the interface characteristics between the substrate crystal and formed crystal and impurities addition characteristics to be improved.
