Abstract:
A method of manufacturing a calorimeter, comprising the steps of:providing a substrate having a tri-layer structure comprised of an etching layer, an etching stop layer, and a support substrate; etching the etching layer to form a hollow portion in a surface of the etching layer; depositing a sacrificial layer in the hollow portion of the etching layer; flattening the surface of the etching layer; forming an insulating film on the flattened surface of the etching layer; etching the insulating film; forming an absorber over the insulating film for absorbing radiation energy and converting the radiation energy into thermal energy; forming a resistor between the absorber and the insulating film for converting thermal energy into an electrical signal; and etching the sacrificial layer and the etching layer to form a membrane for controlling a thermal discharge from the resistor.
