Title: Power module metal case
Inventor: MAEDA MASAHIRO
IPC: H01L23/36
Filed: 1991-03-29
Abstract: PURPOSE:To enhance a semiconductor in thermal conductivity so as to restrain the semiconductor from rising in temperature by a method wherein the surface of a heat dissipating plate in which a printed board and the semiconductor requiring heat dissipation are fixed with solder is plated with solder. CONSTITUTION:A printed board 6 mounted with a solder chip and a power semiconductor is fixed to a heat dissipating plate 1 whose surface is plated with solder or the like. A second stage semiconductor requiring heat dissipation is directly fixed to the heat dissipating plate 1 with solder through a hole provided to the printed board 6. Therefore, as the solder-plated heat dissipating plate 1 is better than a conventional nickel-plated heat dissipating plate in wettability to solder, the second stage semiconductor 7 is enhanced in fixedness. By this setup, a semiconductor 7 is enhanced in thermal conductivity, so that it can be restrained from rising in temperature.

Abstract: PURPOSE:To enable the thin formation of light receiving elements using inexpensive filters, by arranging photoelectric elements respectively behind visible light filters and infrared transmission filters arranged in proximity to a subtractor connected to both the elements to obtain a light receiving output as difference of voltage proportional to outputs thereof. CONSTITUTION:A photoelectric element PD1 is arranged behind an optical filter F1 and a photoelectric element PD2 behind an optical filter F2.

Current-voltage conversion circuits A1 and A2 connected to the elements PD1 and PD2 output voltages E1 and E2 proportional to the photocurrent flowing through the elements PD1 and PD2 and a subtractor A3 connected thereto outputs an voltage E3 of E1-E2 by R3=R5=R4=R6. So to speak, as the spectroscopic sensitivity characteristic is almost equal in the wavelength range longer than the near infrared rays between both the visible light and infrared rays transmission filters, the output can be obtained corresponding to the characteristic of the visible light range in the visible light filter as subtractor output.
