    摘要： A monolithic integrated circuit and method includes a substrate, a plurality of semiconductor device layers monolithically integrated on the substrate, and a metal wiring layer with vias interconnecting the plurality of semiconductor device layers. The semiconductor device layers are devoid of bonding or joining interface with the substrate. A method of fabricating a monolithic integrated circuit using a single substrate, includes fabricating semiconductor devices on a substrate, fabricating at least one metal wiring layer on the semiconductor devices, forming at least one dielectric layer in integral contact with the at least one metal wiring layer, forming contact openings through the at least one dielectric layer to expose regions of the at least one metal wiring layer, integrally forming, from the substrate, a second semiconductor layer on the dielectric layer, and in contact with the at least one metal wiring layer through the contact openings, and forming a plurality of non-linear semiconductor devices in said second semiconductor layer.

    摘要： A hard mask is formed on an interconnect structure comprising a low-k material layer and a metal feature embedded therein. A block polymer is applied to the hard mask layer, self-assembled, and patterned to form a polymeric matrix of a polymeric block component and containing cylindrical holes. The hard mask and the low-k material layer therebelow are etched to form cavities. A conductive material is plated on exposed metallic surfaces including portions of top surfaces of the metal feature to form metal pads. Metal silicide pads are formed by exposure of the metal pads to a silicon containing gas. An etch is performed to enlarge and merge the cavities in the low-k material layer. The metal feature is protected from the etch by the metal silicide pads. An interconnect structure having an air gap and free of defects to surfaces of the metal feature is formed.
