Patent ID: 8759926

Claim:
A semiconductor physical quantity sensor comprising: a sensor unit including: a support substrate having a surface made of an electrically insulating material; a first semiconductor substrate divided into a predetermined shape to include a sensor structure, a sensor peripheral portion and a connector portion, the sensor peripheral portion having a loop-shape entirely surrounding a periphery of the sensor structure and the connector portion; a pattern portion disposed along a surface of the first semiconductor substrate, the pattern portion including a wiring pattern as a wiring and a peripheral pattern, the wiring pattern electrically connecting the sensor structure and the connector portion, and the peripheral pattern having a loop shape entirely surrounding a periphery of the sensor structure and the connector portion, and being electrically connected to the sensor peripheral portion, wherein the wiring pattern and the peripheral pattern are bonded to the surface of the support substrate to join the first semiconductor substrate and the support substrate to each other, and the peripheral pattern is located between the sensor peripheral portion and the support substrate; a cap having a substantially plate shape and bonded to the first semiconductor substrate on an opposite side of the support substrate to hermetically seal the sensor structure; a first penetrating electrode that passes through the support substrate in a layering direction in which the first semiconductor substrate and the support substrate are layered and is electrically connected to the wiring pattern, and a third penetrating electrode that passes through the support substrate in a layering direction in which the first semiconductor substrate and the support substrate are layered, and is electrically connected to the sensor peripheral portion through the peripheral pattern.
