Patent ID: 8516892

Claim:
A pressure sensor module comprising: a pressure sensor; the pressure sensor comprising: a semiconductor substrate; a cavity; a pressure-sensitive element; and a conductive section, wherein the cavity is disposed inside the semiconductor substrate and arranged substantially along a face of the semiconductor substrate at a substantially central area of the face such that a thin-plate region of the semiconductor substrate is provided at one side of the cavity, the thin-plate region being defined as a diaphragm, wherein the pressure-sensitive element is arranged at the diaphragm, wherein the conductive section is electrically connected to the pressure-sensitive element and is disposed on the face of the semiconductor substrate at a region excluding the diaphragm; and a laminated substrate including a wiring base material on which the pressure sensor is mounted, wherein a face of the wiring base material on which the pressure sensor is mounted is disposed inside the laminated substrate such that the face of the wiring base material has an exposed area from the laminated substrate.
