Abstract:
Provided is a semiconductor pressure sensor that can maintain high reliability and measure pressure with high accuracy without increasing the size thereof and that has hydrogen permeation prevention performance. The semiconductor pressure sensor includes: a first semiconductor substrate having a recess formed thereon; a second semiconductor substrate joined to the first semiconductor substrate with an oxide film interposed therebetween; a reference pressure chamber formed as a space surrounded by the recess of the first semiconductor substrate and the second semiconductor substrate; a piezoresistor formed on a surface of the second semiconductor substrate that receives pressure, along an outer periphery of the reference pressure chamber; and a protective film formed on the surface of the second semiconductor substrate that receives pressure, and side surfaces of the second semiconductor substrate and the oxide film.

Claim (Index 5):
The semiconductor pressure sensor according to  claim 3 , wherein the number of the silicon nitride films SiNx laminated in the multilayer film is 5 to 10.
