Abstract

Stereolithographically fabricated conductive elements and semiconductor device components and assemblies including these conductive elements. The conductive elements may include multiple superimposed, contiguous, mutually adhered layers of a conductive material, such as a thermoplastic conductive elastomer or a metal. In semiconductor device assemblies, the stereolithographically fabricated conductive elements may electrically connect semiconductor device components to one another. The conductive elements may alternatively comprise conductive traces or vias of circuit boards or interposers. A stereolithographic method for fabricating the conductive elements may include use of a machine vision system with at least one camera operably associated with a computer controlling a stereolithographic application of material so that the system may recognize the position, orientation, and features of a semiconductor device assembly, semiconductor die, or other substrate on which the conductive element is to be fabricated.
