Patent ID: 8410427

Claim:
An apparatus for manufacturing a semiconductor device including a semiconductor substrate and a lower surface electrode in which an aluminum containing layer, a titanium layer, a nickel layer, and a nickel oxidation-prevention layer are laminated in order from a semiconductor substrate side, the apparatus comprising: a sputtering apparatus; a detector that detects a partial pressure of oxygen in a chamber of the sputtering apparatus; a decompressor that adjusts the partial pressure of oxygen in the chamber; and a controller that is electrically connected to the decompressor and the detector, and controls the decompressor according to a detected value of the detector and decreases the partial pressure of oxygen in the chamber to be within equal to or more than 3×10 −6 Pa and equal to or less than 5×10 −6 Pa when the sputtering apparatus forms the titanium layer by sputtering.
