ABSTRACT:
An alumina substrate has a front surface with a semiconductor gas sensor main body attached thereon for specific detection of a surface exposed gas, and has a rear surface formed with a glass layer and a gold paste layer as superposed on the surface, and bonded to a gold plating layer on a frame by parallel gap welding. The gold paste layer is welded to the gold plating layer with the heat of welding. The glass layer prevents transmission of thermal impact of die bonding to the substrate.
