An architecture for creating a vertical JFET. Generally, an integrated circuit
structure includes a semiconductor area with a major surface formed along a plane
and a first source/drain doped region formed in the surface. A second doped region
forming a channel of different conductivity type than the first region is positioned
over the first region. A third doped region is formed over the second doped region
having an opposite conductivity type with respect to the second doped region, and
forming a source/drain region. A gate is formed over the channel to form a vertical JFET.
In an associated method of manufacturing the semiconductor device, a first source/drain
region is formed in a semiconductor layer. A field-effect transistor gate region,
including a channel and a gate electrode, is formed over the first source/drain
region. A second source/drain region is then formed over the channel having the
appropriate conductivity type.
