摘要

A semiconductor pressure-detecting apparatus includes a semiconductor chip having a diaphragm and a frame molded within a resin with the diaphragm exposed. A reference pressure chamber may be provided between the diaphragm and the frame. Since the diaphragm is exposed, a medium, the pressure of which is to be measured, easily contacts the diaphragm. Therefore, if the stem is connected to a case containing the medium, a high pressure can be measured.
