摘要： Method of forming dual gate insulation layers and semiconductor device having dual gate insulation layers is disclosed. The method of forming dual gate insulation layers comprises forming a first thin layer of a thick gate insulation layer on a semiconductor substrate by oxidizing the semiconductor substrate, depositing a second thicker layer of the thick gate insulation layer on the first thin layer, removing a portion of the thick gate insulation layer to expose a surface area of the semiconductor substrate and forming a thin gate insulation layer on the exposed surface area of the semiconductor substrate. The method of forming dual gate insulation layers, when applied in fabricating semiconductor devices having dual gate insulation layers and trench isolation structures, may help to reduce a silicon stress near edges of the trench isolation structures and reduce/alleviate/prevent the formation of a leaky junction around the edges of the trench isolation structures.

摘要： A holographic detection device for a content of a gas in a GIS switch includes a laser and a data process system. The laser includes a laser emitter and a laser receiver which are fixed at a sampling port of the GIS switch and connected with the data process system. A holographic detection method for a content of a gas in a GIS switch includes emitting a laser beam towards the inside of the GIS switch; receiving the laser beam from the inside of the GIS switch, and calculating a content of hydrogen fluoride gas inside the GIS switch according to an intensity of the emitted laser beam and an intensity of the received laser beam. Since the laser beam goes through the inside of the GIS switch, there is a small error in the detection result, which thus can reflect a real state inside the GIS switch.
