  • Publication number: 20250072095
    Abstract: A terminal structure with optimized reliability for a power semiconductor device, a preparation method therefor, application thereof, a power device and a preparation method therefor are provided. The terminal structure includes a phosphorus-doped silicon oxide layer, a silicon nitride layer, a silicon-rich silicon nitride semi-insulating layer, an undoped silicon dioxide layer, and an organic medium layer. The silicon-rich silicon nitride semi-insulating layer is of an alternating superposition structure of a silicon-rich silicon nitride layer and an ultra-thin silicon nitride barrier layer. The terminal structure effectively prevents external moisture from invading the power device, which improves the robustness of the power device under a moisture condition. The multi-layer silicon-rich silicon nitride is used as a semi-insulating layer, which makes an electric field on a surface of the power device evenly distributed in gradient, prevents the electric field from being gathered at a device terminal.

  • Patent number: 12209057
    Abstract: A preparation method of a polymer-derived high-temperature ceramic thin film sensor is provided. Specifically, a sensitive layer precursor layer is prepared by spraying a sensitive layer precursor liquid on an alumina substrate, and the sensitive layer precursor liquid is obtained by mixing precursor liquid with conductive powder. A protective layer precursor liquid is prepared by spraying protective layer precursor liquid on the sensitive layer precursor layer, and the protective layer precursor liquid is obtained by mixing TiB2 nano-powder, insulating powder and the precursor liquid. The protective layer precursor layer, a solder and the sensitive layer precursor layer are simultaneously pyrolyzed by a one-time pyrolysis process, and thus a protective layer, the solder joints and the sensitive layer are obtained simultaneously. Thus, there is no need to pyrolyze the sensitive layer first, saving the time for pyrolyzing the sensitive layer.
