Title: Semiconductor device and photodetector
Inventor: MARUYAMA YASUHIRO
IPC: H01L21/8222
Filed: 2002-09-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device whose transistor hardly operates improperly even when noise is applied to a power supply voltage and to provide a photodetector equipped with it.  <P>SOLUTION: A semiconductor element structure 10 includes a resistor R1 and an output transistor QP1. A resistor layer 13 of the resistor R1 and a base terminal 17a of the output transistor QP1 are connected through a metal layer 15. A power supply voltage Vcc applied to the resistor R1 is also applied to an emitter terminal 17c of the output transistor QP1. Since an island region 12 of the resistor R1 is floating and produces no parasitic capacity, the output transistor QP1 does not improperly operate even noise is applied to the power supply voltage Vcc.  <P>COPYRIGHT: (C)2004,JPO
