Pressure sensor component

摘要

The pressure sensor component has a chip carrier carrying a semiconductor chip with an integrated pressure sensor having a pressure-detecting surface exposed to the pressure to be measured. A device encapsulation made from an electrically insulating material surrounds the entire assembly except for protruding electrode terminals. Bond wires connect the electrode terminals with the pressure sensor and/or the electronic circuit of the semiconductor chip. The device encapsulation consists entirely of a homogeneous pressure-transmitting medium comprising an enveloping compound, which transmits the pressure to be measured as free from delay and attenuation as possible but is mechanically resistant and dimensionally stable. The pressure to be measured is transmitted directly by the enveloping compound onto the pressure-detecting surface of the semiconductor chip, and the pressure sensor and/or the pressure sensor component is covered tightly on all sides against mechanical and/or chemical influences.
