Title: Rear surface incident photodetector
Inventor: WAKABAYASHI ATSUSHI
IPC: H01L31/02
Filed: 1992-07-28
Abstract: PURPOSE:To enhance characteristics of element by filling the gap between a package frame and the surface and side face of a photodetector element with thermally conductive intermediate thereby cooling the photodetector element sufficiently. CONSTITUTION:In a rear surface incident infrared solid image sensor, intermediate 10 is filled in a space defined by a photodetector element 7, a rib 5a, and a package frame 5. Four side faces and the surface of the photodetector element 7 are covered entirely with the thermally conductive intermediate 10 which also contacts with the inner face of the package frame 5. In other words, the intermediate 10, e.g. an insulating epoxy resin, fills the gaps between four side faces of the photodetector element 7 and the package frame 5 while furthermore fills many parts of underneath space horizontally. Consequently, a second heat dissipation channel is additionally provided routing from the surface or the side face of element through the intermediate 10 to the package frame 5. Furthermore, the photodetector element 7 can be replaced easily because the photodetector 7 is separated from a cooling head 23 by means of a bottom plate 6.
