Patent ID: 8122768

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; a bump electrically connected to the conductive section; and a laminated substrate including a wiring base material electrically connected to the pressure sensor via the bump, wherein the wiring base material is disposed inside the laminated substrate, and a face of the wiring base material is electrically connected to the bump and has an exposed area from the laminated substrate.
