Title: Method for making a metallic compound film
Inventor: JONG JAE-IN
IPC: C23C14/46
Filed: 1992-12-28
Granted: 1995-05-10
Abstract: The method improves reproducibility of metallic compound film by controlling inflow of reacting gases and ionized current. The method comprises (A) placing the substrate by substrate holder (5); (B) fixing the position of evaporating sources (2,2') and ionized electrodes (4,4'); (C) degasing using diffusion pump in vacuum chamber (1); (D) generating arc by applying 40 to 140 voltage to the ionized electrodes (4,4'); (E) ion-plating by introducing reacting gases through guiding tubes (8).
