Methods for consolidating previously unconsolidated conductive material to form conductive structures or contact pads or secure conductive structures to contact pads

Abstract

Methods for fabricating conductive structures on contact pads of semiconductor device components or other electronic components and for securing conductive structures to contact pads include directing consolidating energy toward unconsolidated conductive material. Alternatively, an unconsolidated material that will consolidate without additional consolidating energy may be used to form such conductive structures, in which case layers of the unconsolidated material are merely defined. Consolidating energy may be directed or layers of unconsolidated conductive material defined by recognizing the locations or orientations of one or more features, such as a contact, of the semiconductor device component or other electronic component. The conductive elements may include, but are not limited to, discrete conductive structures that protrude from the contacts, conductive traces that extend laterally from the contacts, or vias of circuit boards, interposers, or semiconductor devices.
