Abstract
In various embodiments this disclosure is directed to conductive adhesives layers that can be used, in one example embodiment, to connect one or more shielding structures (for example, metal cans and/or covers) to a semiconductor package to enclose one or more electronic components on the semiconductor package. In another embodiment, the conductive adhesive layers disclosed herein can be used in connection with optoelectronic devices (for example, optoelectronic devices including laser diodes and/or avalanche photodiodes, APDs). In one embodiment, the conductive adhesives can additionally be used for thermal dissipation and for electrical contact in connection with one or more electronic components on a semiconductor package. In one embodiment, various materials including, spray prints, conductive paste, inks (for example, sintering silver-based materials), epoxy material (for example, epoxy materials filled with silver and/or other metal particles) can be used to provide a conductive adhesive layer.
