  • Method of making a MOS-gated semiconductor device with a single diffusion
    Patent number: 6080614
    Abstract: A method of fabricating a MOS-gated semiconductor device in which arsenic dopant is implanted through a mask to form a first layer, boron dopant is implanted through the mask to form a second layer deeper than the first layer, and in which a single diffusion step diffuses the implanted arsenic and the implanted boron at the same time to form a P+ body region with an N+ source region therein and a P type channel region.
    Type: Grant

  • Method of making MOS-gated semiconductor devices
    Patent number: 5877044
    Abstract: A gate electrode control structure of an MOS-gated semiconductor device includes four doped regions including a first (source) region forming a first P-N junction with an enclosing composite region comprising a second, lightly doped (channel) region wholly enclosing a third heavily doped (body) region partly enclosing the first region, and a fourth (drain) region forming a P-N junction with the third region. The gate electrode control structure is fabricated using known gate electrode self-alignment doping processes but wherein, in the process for forming the third heavily doped region, a spacer layer is provided on the gate electrode for defining a spacing between the third region and the channel region with an improved degree of precision.
