Title: Thermal type infrared ray sensor
Inventor: MIYAWAKI YASUO
IPC: G01J1/02
Filed: 1991-05-08
Abstract: PURPOSE:To improve incident infrared ray utilization efficiency and reduce the loss of incident infrared rays in element spacing by equipping a light reception part having a larger area than a projection area for the infrared ray incident direction of a thermal part. CONSTITUTION:A thermal part is constituted of an electrode 5 which is formed on the inner wall of a recessed part 8 which is provided on a pyroelectric body substrate 7 and a pyroelectric body which is sandwiched by it. Then, a light reception part 2 constituting an element and the thermal part are clearly separated, thus reducing the efficiency for converting incident infrared rays to electric signal. However, in a compact or an integrated type infrared ray sensor, the element itself becomes small, thus reducing the distance between the light reception part 2 and the thermal part and suppressing efficiency reduction. On the other hand, by increasing the projection area for the infrared ray incident direction of the light reception part 2 as compared with that of the thermal part, incident infrared rays can be utilized effectively and the strength of output electric signal can be improved.
