Abstract
본 발명은 다수의 적층구조를 갖는 후막형 가스센서에 관한 것으로 그 기술적인 구성은, 기판(1)상에 양측으로 저항변화 검출용 적극인 센서소자 전극(2)을 개재하여 일정두께의 후막(3)이 형성되며, 그 상측에는 절연체층(4)을 개재하여 양측에 센서소자 전극(2')이 마련된 후막(3')이 순차로 다수의 층으로 적층토록 되며, 상기 기판(1)의 하측에는 발열체 전극(5)을 개재하여 발열체(6)가 형성되는 것이다.The present invention relates to a thick film-type gas sensor having a plurality of laminated structures, the technical configuration of which is a thick film having a predetermined thickness through a sensor element electrode (2) which is an active electrode for detecting resistance change on both sides of the substrate (1). 3) is formed thereon, and the thick film 3 'having the sensor element electrodes 2' provided on both sides of the substrate 1 through the insulator layer 4 is sequentially stacked in a plurality of layers. The heating element 6 is formed on the lower side via the heating element electrode 5.
이에 따라서, 복수층으로 형성된 후막에 의해 별도의 조성이 필요 없이도 서로 다른 다종류의 특성가스를 검출할 수 있게됨은 물론, 하나의 감응체로서 가스의 선택성을 부여하여 다양한 센싱특성을 얻을 수 있게되며, 이에 따라 가스센서의 특성을 향상시킬수 있는 것이다.Accordingly, the thick film formed of a plurality of layers enables to detect different kinds of characteristic gases without the need for a separate composition, as well as to provide a variety of sensing characteristics by providing a selectivity of the gas as one sensitive body. Therefore, the characteristics of the gas sensor can be improved.
