Abstract:
1. A multi-mode thin film deposition apparatus, comprising: a reaction chamber, having a first opening and a second opening penetrating through the reaction chamber, the first opening and the second opening having a same axial direction; a carrying seat, disposed in the reaction chamber and suitable to carry a substrate; a first gas inflow system, connected to the first opening and suitable to supply a first process gas during a first thin film deposition process mode; a showerhead, having a gas mixing room and a plurality of gas holes, wherein the plurality of gas holes is disposed at a side of the reaction chamber and faces to the carrying seat, and the gas mixing room is connected to the reaction chamber through the plurality of gas holes; an inert gas supplying source, connected to the gas mixing room of the showerhead and suitable to supply an inert gas which is non-reactive to the first process gas; a second gas inflow system, connected to the gas mixing room of the showerhead and suitable to supply a second process gas during a second thin film deposition process mode; and a first voltage supplying source connected to the showerhead and suitable to supply a radio frequency bias voltage to the second process gas so as to produce a plasma.
