    • An integrated Junction Field Effect Transistor is disclosed which is much smaller and much less expensive to fabricate because it does not use Shallow Trench Isolation or field oxide in the semiconductor substrate to isolate separate transistors. Instead, a layer of insulating material is formed on the top surface of said substrate, and interconnect trenches are etched in said insulating layer which do not go all the way down to the semiconductor substrate. Contact openings are etched in the insulating layer all the way down to the semiconductor layer. Doped poly-silicon is formed in the contact openings and interconnect trenches and silicide is formed on tops of the poly-silicon. This contact and interconnect structure applies to any integrated transistor. The integrated JFET disclosed herein does not use STI or field oxide and uses junction isolation. A conventional JFET is built in a P- well. The P- well is encapsulated in an N-well which is implanted into the substrate. Separate contacts to the P-well, N-well and substrate are formed as well as to the source, drain and gate so that the device can be isolated by reverse-biasing a PN junction. Operating voltage is restricted to less than 0.7 volts to prevent latching.
