Abstract:
1. A method of fabricating a base layer circuit structure comprising: providing an alignment carrier comprising a support surface; forming a plurality of electrically conductive structures above the support surface of the alignment carrier, each electrically conductive structure comprising at least one side surface, and an upper surface; disposing a structural material around and physically contacting the at least one side surface of each electrically conductive structure of the plurality of electrically conductive structures formed above the support surface of the alignment carrier, the structural material having an upper surface substantially coplanar with or parallel to at least one upper surface of at least one electrically conductive structure of the plurality of electrically conductive structures; exposing, if covered, the upper surfaces of the plurality of electrically conductive structures to facilitate electrical connection thereto; and separating the alignment carrier from the base layer circuit structure, the base layer circuit structure comprising the plurality of electrically conductive structures and the structural material surrounding and physically contacting the plurality of electrically conductive structures.
