A method of manufacturing a trench power MOSFET device with improved UIS performance and a high avalanche breakdown voltage is disclosed. The image pickup device comprises a pixel array, a pixel reader, a row selector, a column selector, a gain circuit, a gain selector. An inlet can be operably connected to each turbine vane to form a fluid communication path between a cooling fluid source and an interior of the hollow body of each turbine vane. A plug is configured for engagement with the sleeve at the split region.
