ABSTRACT:
A thin film layer of primarily platinum is deposited onto a ceramic substrate and electrical connections are applied to the platinum layer to form a heater. In a preferred embodiment, the electrical connections comprise two electrically conductive posts fixed to the ceramic substrate at a first end and electrically contacting the platinum heater layer near this first end. Preferably, the heater layer forms mounds at each post and a thinner region therebetween, resulting in a resistance profile which concentrates heating in the thinner region and reduces undesired heating of the post area. Such heaters can be employed individually or in conjunction with other similar heaters.
