Abstract:
A dual-inlaid damascene contact comprising:an electrically conductive layer;a dielectric layer formed on the electrically conductive layer, the dielectric layer having a dual-inlaid cavity formed therein, the dual-inlaid cavity comprising a contact cavity formed in a portion of the dielectric layer, the contact cavity having a bottom surface, first sidewall surfaces, and an opening adjacent to a surface of the dielectric layer, anda via cavity formed in a portion of the dielectric layer, the via cavity having second sidewall surfaces that extend the contact cavity to the electrically conductive layer, the electrically conductive layer having a via surface defined by an exposed portion of the electrically conductive layer adjacent to the via cavity;a damascene contact disposed in the dual-inlaid cavity and in electrical communication with the electrically conductive layer, the damascene contact extending from the via surface to a contact surface adjacent to the opening of the contact cavity; anda semiconductor layer formed on the surface of the dielectric layer and positioned over a portion of the contact surface and in electrical communication with the contact surface, whereby the damascene contact forms an interconnect structure between the electrically conductive layer and the semiconductor layer.
