Abstract:
1. A semiconductor structure comprising: a monocrystalline semiconductor body comprising: a first dielectric layer laterally surrounding said horizontal section; a second dielectric layer on said horizontal section and extending laterally from said first vertical section to said second vertical section, said first dielectric layer and said second dielectric layer having essentially co-planar top surfaces and said second dielectric layer being thinner than said first dielectric layer; a first gate wrapping around said first vertical section at said first channel region so that, on first opposing sides of said first vertical section, said first gate is above and immediately adjacent to said co-planar top surfaces of said first dielectric layer and said second dielectric layer; a second gate wrapping around said second vertical section at said second channel region so that, on second opposing sides of said second vertical section, said second gate is above and immediately adjacent to said co-planar top surfaces of said first dielectric layer and said second dielectric layer; a third dielectric layer on said second dielectric layer above said horizontal section and extending laterally from said first gate to said second gate; and, a shared source/drain region contact extending vertically through said third dielectric layer and further through said second dielectric layer to a center portion of said horizontal section such that said shared source/drain contact is positioned laterally between and electrically isolated from said first gate and said second gate.
