Abstract:
An apparatus for forming a thin film which comprises a gas introduction tube for introducing an inert gas into a vacuum chamber, a vapour source and a target, by depositing sputtered particles and evaporated particles on the surface of a substrate, the sputtered particles being liberated by sputtering the target using ion energy of plasma generated around the target while the evaporated particles being obtained by evaporating said vapour source by heating and ionising evaporated particles using the plasma, which is characterised by:a holding part for holding the substrate so that a film-forming surface thereof faces the side wall of the vacuum chamber;a rotating table for rotating the holding part within the vacuum chamber;a target arranged in the side wall of the vacuum chamber so that a sputtering surface thereof faces the inside of the vacuum chamber;a shield detachably fitted in a through hole formed approximately through the centre of the target and having a hollow space therein;a gas introduction tube for introducing the inert gas into the hollow space of the shield; anda vapour source provided in the hollow space near a gas exit of the inert gas introduction tube.
