Abstract

PURPOSE: To make it possible to vapor deposit a decalescent-substance blackened aluminum film to nearly-uniform thickness by arranging a shield at the middle point of the space between a glass face plate and calescent body.
CONSTITUTION: In decalescent-substance film vapor deposition chamber 11c, the distance between glass face plate 1a, which is a vapor-deposited substance, and boron-nitride calescent body 13 is set to 400mm shield 15 of a stainless plate of 230R in upward arc 180ϕ in caliber is arranged at the position right above the center of calescent body 13 of 200mm equivalent to the middle point of the space; and then, calescent body 13 is heated up to approximate 1500°C and aluminum wire 10 is inserted to be vapored and scattered. At this time, aluminium vaporing and scattering more at the middle part of plate 1a right over calescent body 13 sticks to it through the arrangement of shield 15, and the rest scatters, to that blackened aluminum film 5 (of the minimum thickness needed for reducing a doming phenomenon) will be vapor-deposited on photo-reflective metal film 4 to a nearly-uniform film thickness (b) [(a) is conventional one].
