A process and an architecture related to a vertical MOSFET device and a
capacitor for use in integrated circuits. Generally, the integrated
circuit structure includes a semiconductor layer with a major surface
formed along a plane thereof and further including a first doped region
formed in the surface. A second doped region of a different conductivity
type than the first doped region is positioned over the first region. A
third doped region of a different conductivity type than the second
region is positioned over the second region. In one embodiment of the
invention, a semiconductor device includes a first layer of semiconductor
material and a first field-effect transistor having a first source/drain
region formed in the first layer. A channel region of the transistor is
formed over the first layer and an associated second source/drain region
is formed over the channel region. The integrated circuit further
includes a capacitor having a bottom plate, dielectric layer and a top
capacitor plate. In an associated method of manufacture, a first device
region, selected from the group consisting of the source region and a
drain region of a field-effect transistor is formed on a semiconductor
layer. A first field-effect transistor gate region is formed over the
first device region. A capacitor comprising top and bottom layers with a
dielectric layer disposed therebetween, is also formed on the
semiconductor layer. In another embodiment, the capacitor layers are
formed within a trench or window formed in the semiconductor layer.
