Abstract:
1. A semiconductor bridge comprising: a bridge part disposed in contact with a substrate and having a narrowed section above the substrate, the bridge part heated by applying a current along a crosswise direction through a narrowed section of the bridge part and formed on the substrate and above the substrate, the narrowed section including a first layer and an ignition bridge layer, the first layer being formed on the substrate, having insulating properties, and containing SiO the ignition bridge layer being formed on the first layer and serving as a second layer above the first layer and above the substrate; wherein a width in a direction perpendicular to the crosswise direction of the bridge part at the first layer and a width in a direction perpendicular to the crosswise direction of the bridge part at the second layer are substantially equal to each other, wherein a side face and an upper face of the bridge part are exposed outwardly, wherein the first layer has a thermal conductivity of 50 W/m·K or less, an electrical resistivity of 10 wherein the substrate is made of silicon, a surface of the substrate is provided with an oxide film, and the first layer is an oxide film of SiO
