  • Arrangemenet in a power MOS transistor
    Publication number: 20020027242
    Abstract: To reduce parasitic capacitances between drain and source electrodes, respectively, and gate electrodes in a power MOS transistor, the drain and the source electrodes (D′, S′) are located below the gate electrodes (G) in the transistor.
    Type: Application

  • Planar trenches
    Patent number: 6063693
    Abstract: Method for improving the topography over trench structures in which the provision of extra poly-semiconductor material e.g. polysilicon or nitrate or oxide in the regions of the trench edges and, if necessary, the subsequent oxidation of the extra material prevents the occurrence of regions of high mechanical stress.
    Type: Grant
