摘要: In the present invention, an etching hole 21 is formed in a polysilicon film 14 as a cavity-wall member. Through the etching hole 21, hydrofluoric acid is injected, so as to dissolve a silicon oxide film 13, thereby forming a cavity 22. In the cavity 22, a detecting unit 12 of a sensor is in an exposed condition. Next, by sputtering, an Al film 16 is deposited in the etching hole 21 and on an upper face of a substrate. Thereafter, a portion of the Al film 16 positioned on the polysilicon film 14 is removed by etching back, thereby leaving only a metal closure 16a of Al which closes the etching hole. The sputtering step is performed under a pressure of 5 Pa or less, so that the pressure in the cavity can be held to be low.
