A method for forming a self-aligned contact to an ultra-thin body
transistor first providing an ultra-thin body transistor with source and
drain regions operated by a gate stack; forming a contact spacer on the
gate stack; forming a passivation layer overlying the transistor; forming
a contact hole in the passivation layer exposing the contact spacer and
the source/drain regions; filling the contact hole with an electrically
conductive material; and establishing electrical communication with the
source/drain region.
