Title:
OPTICAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2010/079686
Kind Code:
A1
Abstract:
Disclosed is an infrared sensor (1) comprising a bolometer element (11) and a reference element (21), wherein the reference element (21) comprises a bolometer film (22), a substrate-side insulating film (31) which is formed on the substrate-side surface of the bolometer film (22), a heat dissipation film (23) which is composed of amorphous silicon and formed on the substrate-side surface of the bolometer film (22) with the substrate-side insulating film (31) interposed therebetween, and a plurality of heat dissipation columns (25) which are composed of amorphous silicon and thermally connected with the heat dissipation film (23) and a substrate (10). The bolometer film (22) and the substrate-side insulating film (31) are so formed as to stretch out to and cover the lateral surface of the heat dissipation film (23), said lateral surface meeting with the surface of the substrate (10). The infrared sensor (1) can be reduced in size, while efficiently reducing the effect of temperature changes in the environment where the infrared sensor (1) is used.
