Abstract:
A fin structure is on a substrate. The fin structure includes an epitaxial region having an upper surface and an under-surface. A contact structure on the epitaxial region includes an upper contact portion and a lower contact portion. The upper contact portion includes a metal layer over the upper surface and a barrier layer over the metal layer. The lower contact portion includes a metal-insulator-semiconductor (MIS) contact along the under-surface. The MIS contact includes a dielectric layer on the under-surface and the barrier layer on the dielectric layer.

Claim (Index 1):
A method comprising:\n forming a neighboring pair of fin structures on a substrate, the fin structures each comprising an epitaxial region extending above an isolation region disposed between the fin structures; conformally forming a first etch stop layer over the fin structures and the isolation region; forming a second etch stop layer on the first etch stop layer and on upper surfaces of the epitaxial regions, the second etch stop layer merging between the fin structures, the merging of the second etch stop layer forming an enclosed void between the fin structures; removing a portion of the first etch stop layer from under-surfaces of the epitaxial regions; and forming first contacts on portions of the upper surfaces of the epitaxial regions and second contacts on portions of the under-surfaces of the epitaxial regions, wherein the first contacts are a first type of contact and the second contacts are a second type of contact different from the first type of contact.
