Abstract:
1. A semiconductor unit, comprising: a semiconductor chip; a ceramic substrate having a circuit pattern on which the semiconductor chip is mounted; a temperature sensor in contact with the circuit pattern for detecting a temperature of the semiconductor chip; a support plate that provides a mount for said temperature sensor and presses the temperature sensor against the ceramic substrate; a metal base on which the ceramic substrate is mounted; and a frame made of a non-conductive material and mounted on the metal base so as to surround the ceramic substrate, wherein the support plate presses the temperature sensor against the circuit pattern on which the semiconductor chip is mounted, wherein the support plate is a leaf spring, wherein the support plate is fixed to the frame, and wherein the support plate is mounted on the metal base so as to project over the ceramic substrate from the frame, and the temperature sensor is mounted on the projecting end of the support plate and pressed against the ceramic substrate.
