Abstract

PURPOSE:To make a vacuum tank compact by putting a crucible into a vessel for ion cluster beam source from the upper part and attaching this crucible to the vessel by using a crucible-fixing means so as to obviate the necessity of providing a spacing for taking a crucible in and out. CONSTITUTION:In thin film-forming equipment, a crucible-fixing means is constituted of a column 15 and guide parts 14. The two guide parts 14 are provided protrudingly and concentrically at a space to the bottom of a vessel 3 for ion cluster beam. The column 15 is integrally attached to the bottom of a crucible 7, and a mounting plate 15a is formed at the lower end of the column 15. The crucible 7 is put into the vessel 3 from the upper part of the vessel 3. When the crucible 7 is turned, the mounting plate 15a is brought into elastic contact and allowed to engage with the guide parts 14 as the plate 15a is turned, by which the crucible 7 can be set in the prescribed position in the vessel 3.
