摘要： Wafer level packaging (WLP) packages semiconductor dies onto a wafer structure. After the wafer level package is complete, individual packages are obtained by singulating the wafer level package. The resulting package has a small form factor suitable for miniaturization. Unfortunately conventional WLP have poor heat dissipation. An interposer with a thermal pad can be attached to the semiconductor die to facilitate improved heat dissipation. In one embodiment, the interposer can also provide a wafer substrate for the wafer level package. Furthermore, the interposer can be constructed using well established and inexpensive processes. The thermal pad attached to the interposer can be coupled to the ground plane of a system where heat drawn from the semiconductor die can be dissipated.

摘要： A barrier layer can be attached in a semiconductor package to one or more sensitive devices. The barrier layer can be used to obstruct tampering by a malicious agent attempting to access sensitive information on the sensitive device. The barrier layer can cause the sensitive device to become inoperable if physically tampered. Additional other aspects of the protective packaging provide protection against x-ray and thermal probing as well as chemical and electrical tampering attempts.

摘要： The addition of thermal conduits by bonding bond wires to bond pads either in a wire loop configuration or a pillar configuration can improve thermal dissipation of a fabricated die. The thermal conduits can be added as part of the normal packaging process of a semiconductor die and are electrically decoupled from the circuitry fabricated on the fabricated die. In an alternative, a dummy die is affixed to the fabricated die and the thermal conduits are affixed to the dummy die. Additionally, thermal conduits can be used in conjunction with a heat spreader.

摘要： There is provided a system and method for a copper stud bump wafer level package. There is provided a semiconductor package comprising a semiconductor die having a plurality of bond pads on an top surface thereof, a plurality of metallic stud bumps mechanically and electrically coupled to said plurality of bond pads, and a plurality of solder balls mechanically and electrically coupled to said plurality of metallic stud bumps. Advantageously, the metallic stud bumps may be provided using standard wirebonding equipment, avoiding the conventional wafer level package requirement for photolithography and deposition steps to provide a multi-layer metallic routing structure. As a result, reduced cycle times, lower cost, and reduced complexity may be provided. Alternative fabrication processes utilizing metallic stud bumps may also support multi-die packages with dies from different wafers and packages with die perimeter pads wirebonded to substrates.
