Title: Light receiver
Inventor: OIMURA KATSUHIKO
IPC: H01L31/0203
Filed: 1998-09-30
Granted: 2001-04-11
Abstract: The present invention provides a light receiver which can not only eliminate the generation of self-directed noise but also effectively reduce the external noise. A P-type diffusion layer is formed on the surface of N-type semiconductor substrate. A P-type low resistance layer is formed on the surface of P-type diffusion layer. A lead frame is formed on the back of N-type semiconductor substrate through the insulating resin film for electrically connecting the P-type low resistance layer and the lead frame. Therefore, the surface of the light receiver can be kept on the grounding potential for preventing the external electromagnetic noise, that is, preventing the external noise and extending the receiving distance. Further, the connection portion between the P-type diffusion layer and P-type low resistance layer is of non-PN junction, thereby sufficiently eliminating the occurrence of self-directed noise.
