Title:
SEMICONDUCTOR INSULATOR
Document Type and Number:
Japanese Patent JPS61180571
Kind Code:
A
Abstract:
PURPOSE:To improve the noise reducing effect and heat transfer characteristic by interposing a capacitor between a portion that the potential of a semiconductor circuit is stable and a metal plate. CONSTITUTION:When a semiconductor 6 is, for example, a transistor, a portion that the potential of a circuit connected with the semiconductor 6 is stable and the first metal plate 1 are connected by a capacitor 8 having sufficiently larger capacity than the floating capacity 7 interposed between the collector and the plate 1. The first plate 1 does not become the primary charger by the capacitor 8, and the insulation between the first and second metal plates 1, 2 and the semiconductor 6 is sufficient merely by electrically separating them.
