Abstract
A vacuum evaporation apparatus has a melting pot containing evaporating material therein and a movable partition. A surface of the evaporating material is separated into a supplying surface (whereinto a Cr-Co material rod of replenishing material is supplied) and an evaporating surface (whereonto an electron beam is irradiated) by the partition only during deposition of evaporating material onto a substrate. After finish of the deposition, the partition is lifted and is apart from the surface.
