    • PURPOSE: A differential hot wire air gauge is provided for accurately measuring small distances using flow sensing in the photo lithograph for a semi conductive production. CONSTITUTION: A device and method for accurately measuring small distances using gas flow sensing. The gas flow sensing system for control a distance between probe and target surface, includes the two hot wires situated on two independent gas stream. The device has both a measurement and a reference gaging conduit, each including a hot-wire anemometer. The differential sensing achieved by use of the reference filters out changes in the gas property. The matched physical configuration of the reference and the measurement gas flow paths minimizes sensitivity of the system to acoustic disturbances. High-mass high thermal conductivity support needles significantly improve the response time for the hot-wires. A sintered metal diffuser in the gas flow path reduces the noise originating in the gas supply
