Title: Ion implantation apparatus
Inventor: WADA TAKAHIRO
IPC: H01J37/04
Filed: 2000-10-30
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate low energy contamination when an ion is implanted. SOLUTION: An ion beam irradiated from an ion source part 1 passes a mass spectrometry part 2, then a specific category of an ion is selected. The selected ion beam is accelerated by an acceleration part 3, and arrives on a surface of a semiconductor base unit placed on an end station part 6 under a condition that the ion beam is made a prescribed implantation energy. In this way, the ion implantation to the semiconductor base unit is carried out. In a route of this ion beam, a thin film 22 to eliminate the low energy contamination is set. Under the condition that the low energy contamination included in the ion beam is blocked by the thin film, the ion beam is implanted into the semiconductor base unit.  Because the implantation of the contamination inside the base unit is blocked, the contamination going through this oxide film, even in the case of a thin gate oxide film, is not implanted. As a result, deterioration of withstand voltage is prevented.
