Filed: 1985-12-18
Abstract: PURPOSE:To prevent heat from being radiated from a heating unit onto a chamber, prevent the substance evaporated from a molecular beam source from being attached to the chamber and facilitate the mounting and dismounting of a cryopanel by providing the top portion of the cryopanel with an opening for inserting a substrate heater and constructing an apparatus such that the molecular beam source and such heating portion as the substrate heater or the like are covered. CONSTITUTION:An apparatus is constructed such that the top of a cryopanel 1 is formed with a hole and a substrate heater 2 is inserted into the opening to enable a film to be formed. Thus, since the total number of the holes in the cryopanel 1 can be reduced, a chamber 5 is not heated by the radiation heat from molecular beam sources 4 and the high temperature portion of the substrate heater 2 and a gas can be prevented from being discharged from the inner wall of the chamber 5. An evaporated substance 9 can be also prevented from being attached to the chamber 5. Further, since the cryopanel 1 can be attached and detached without detaching attaching a manipulator 6, the attaching or detaching operation of the cryopanel 1 can be facilitated.
