ABSTRACT:
A fast response fluid temperature sensor is disclosed which consists of a silicon temperature sensing semiconductor chip mounted on an extremely thin fin having a high surface area to mass ratio. The fin being formed in the shape of a dome to fully enclosed the semiconductor chip and protect the connections thereto from contaminants, mechanical damage and corrosive materials. The fin and chip combination are mounted in a frame assembly, the thermal conductivity of the frame assembly being low and the specific heat thereof being low. Foamed material may be inserted in the dome to further protect the chip and lead thereto from damage.
