Abstract
A semiconductor sensing device has a semiconductor substrate with a pressure sensing bridge circuit including piezo-resistance elements formed on the substrate. Further, the semiconductor sensing device has a temperature sensing bridge circuit including resistance elements formed on the semiconductor substrate. A pair of the resistance elements is connected with a power supply terminal, and the other pair of the resistance elements is connected with a grounding terminal. The resistance elements in either or both of these pairs are formed of different resistance types from each other and of the same conductivity type.
