Abstract:
1. An infrared sensor comprising: a substrate; a sensor unit comprising: a sealing cap secured to said substrate to provide a hermetically sealed space therebetween for accommodating said sensor unit, said sealing cap having a window which passes an incident infrared radiation on said thermal infrared sensing element of said sensor unit; said thermal infrared sensing element having a pair of leads each supported on top of each of said beams to extend along the beam for electrical connection with each corresponding one of said terminal lands, wherein said beams extend in the same plane of said sensor mount in a spaced relation with the top surface of said substrate to carry the respective leads thereon, and said sensor unit further includes a pair of anchor studs each upstanding from each of said terminal lands and secured at its upper end to a distal end of each corresponding one of said leads such that said sensing element is supported on said substrate together, with said sensor mount in a spaced relation from the top surface of said substrate and is electrically connected to said terminal lands through said anchor studs, the upper end of each of said anchor studs being embedded in each corresponding one of said beams so as to have its circumference entirely surrounded by each corresponding one of said beams, and wherein each of said anchor studs is surrounded along its vertical length by each one of sleeves of a porous material.
