Gas sensor and method of fabricating a gas sensor |
摘要 |
A more reliable gas sensor includes a support film formed on a surface of a substrate and a heater electrode. Surrounding the heater electrode is a heater electrical insulation layer 4. Detection electrodes are formed above the electrical insulation layer. A flat insulating layer is formed over the heater insulation layer, and surfaces of the detection electrodes are exposed and flush with the upper surface of the flat insulating layer. A sensitive film is formed above the flat insulating layer in contact with the surfaces of the detection electrodes. A hollow cavity is formed in the substrate.
