Title: Semiconductor position sensor
Inventor: KYOMASU MIKIO
IPC: H01L31/16
Filed: 1992-04-06
Abstract: PURPOSE:To obtain a title device which outputs only a photocurrent corresponding to the light energy of an incident light spot by connecting a bypass resistance formed of a nondoped silicon layer to every microimpurity layer. CONSTITUTION:A photocurrent generated by light incidence into a photodiode Da (i) is fetched according to frequency characteristics having a cut-off frequency determined by a bias resistance R (i) corresponding to this photodiode Da (i) and a coupling capacitance. Hereupon, when the resistance value of the bias resistance R (i) is small, the coupling capacitance is a very small capacitance value, so that resistance cut-off frequency is very high. However, since the bias resistance is formed of a polysilicon layer, a high resistance can be realized; therefore, even when the coupling capacitance is a very small capacitance value, frequency characteristics having a reduction cut-off frequency optimum to fetch a photocurrent can be set, resulting in an improvement in the precision of photocurrent sensing.
