  • Publication number: 20080173096
    Abstract: This invention aims to realize reduction in size without impairing measurement accuracy or connection reliability in a semiconductor pressure sensor in which a glass substrate is adhered to a rear-surface side of a pressure-sensitive chip in which piezoresistive pressure-sensitive gauges have been formed on a front surface of a diaphragm formed of a silicon single crystal to form a space between a rear surface of the diaphragm and the glass substrate, for measuring a pressure applied to the front surface of the diaphragm with reference to a pressure of the first space as a standard pressure. In order to achieve this object, the semiconductor pressure sensor includes resinous projections formed on pressure-sensitive gauge electrodes disposed on a front surface of the pressure-sensitive chip or on wiring from the pressure-sensitive gauge electrodes and bumps formed so as to partially or entirely cover the resinous projections.
