Title: Detecting device of infrared ray and manufacture thereof
Inventor: TANAKA AKIO
IPC: H01L31/0264
Filed: 1987-10-16
Abstract: PURPOSE:To make a device compact and thereby to facilitate handling thereof, by providing a pyroelectric element formed by holding a pyroelectric material film between first and second electrodes. CONSTITUTION:On the occasion of poling a pyroelectric element 35, a drain MD of MOSFET is connected to the ground, and a prescribed poling voltage is impressed on a second electrode 37 of the element 35. When a prescribed pulse is impressed on a gate MG of the MOSFET in this state, the MOSFET is turned ON, and accordingly a voltage for poling is impressed between a first gate 36 and the electrode 37 of the element 35. Therefore a pyroelectric material film 31 is poled to have a pyroelectric function. At the time when an infrared ray is detected, a prescribed reference voltage is impressed on the drain MD and the gate MG is connected to a reset terminal. When the infrared ray enters the material film 31, a change in potential occurs in the electrode 36, the potential of a gate JG of J-FET changes, and so a current flows between a drain JD and a source JS of the J-FET. Accordingly, a signal output in accordance with the incident infrared ray is taken out.
