Abstract:
1. A semiconductor structure comprising: a trench located in a semiconductor substrate; a node dielectric located on a sidewall of said trench; an inner electrode comprising a first doped semiconductor material and located within said node dielectric; an access transistor located on said semiconductor substrate and including an access transistor source region comprising a second doped semiconductor material and contacting said node dielectric; a metal semiconductor alloy portion contacting said inner electrode, said node dielectric, and said access transistor source region; a field effect transistor different from said access transistor, located on said semiconductor substrate, and including another dielectric gate spacer, a source region, and a drain region, wherein said source region and said drain region are laterally surrounded by a shallow trench isolation structure; and at least another metal semiconductor alloy portion located on said source region or said drain region and laterally spaced from at least one of said other dielectric gate spacer and said shallow trench isolation structure.
