Latest Patents
Walter Hansch holds a patent for a semiconductor gas sensor and method for measuring a residual gas proportion with a semiconductor gas sensor. This invention features a gas-sensitive gate electrode that is separated by a gap from a channel region. The sensor is designed as a suspended gate field effect transistor, or alternatively, the gate electrode can be arranged as a first plate of a capacitor. The second plate of the capacitor is connected to the gate of the field effect transistor, which is capacitively controlled. The gate electrode includes a conductive carrier layer with a bearing adhesion promoter layer and a gas-sensitive layer that rests on the adhesion promoter layer. The gas-sensitive layer is composed of a platinum/gold alloy with a gold proportion ranging from 1% to 20%. Additionally, a polymer layer with a thickness of less than 100 nm is formed on the surface of the platinum/gold alloy, and the gap is filled with an oxygen-free gas mixture. Walter Hansch has 1 patent to his name.
