Title: Film formation of superconducting thin film and device thereof, and heater unit used therein
Inventor: KAWAMURA MASAHIRO
IPC: H01L39/24
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To form a film well when a superconductive thin film is formed on a substrate by sputtering while heating a substrate using a heater unit. SOLUTION: In a heater unit 1 for heating a substrate 30 whereon a film is formed, a heat generator 11 is held in one surface side of a transparent member 12 and a heat reflection film 13 is formed in another surface side of the transparent member 12. Therefore, radiation heat from the heat generator 11 is reflected in an interface between the heat reflection film 13 and the transparent member 12 and cast on the substrate 30. Since an interface between the heat reflection film 13 and the transparent member 12 is specular even if a surface of the heat reflection film 13 is deformed, reflection characteristics in the heat reflection film 13 can be made good. Furthermore, a dummy substrate 31 is arranged in the substrate 30 and an outer circumference part thereof in a substrate holder 20. Therefore, even if metal scatters from the substrate holder 20 during sputtering, the scattered metal can be prevented from attaching to the substrate 30.
