A tantalum film was deposited by sputtering followed by a layer of gold by evaporation. The gold layer was first etched after applying a photoresistor to form connecting pads compatible with welding. Resistive networks were formed, also by a process of photo resistance and etching. These were cut with high precision by selective adonization of …
