  • Semiconductor device comprising an over-temperature detection element for detecting excessive temperatures amplifiers
    Patent number: 5629551
    Abstract: A semiconductor device includes on a semiconductor substrate an output transistor which is composed of a collector region, a first base region and a first emitter region, and a temperature detection transistor composed of the collector region, a second base region and a second emitter region. The output transistor is provided at a center of the collector region of the semiconductor substrate. A vacant region is formed on a center of the output transistor, and the temperature detection transistor is provided in the vacant region.
    Type: Grant
    Filed: July 18, 1995
    Date of Patent: May 13, 1997
    Assignee: Matsushita Electric Industrial Co., Ltd.
