摘要:
A semiconductor wafer contains a plurality of semiconductor die with bumps formed over contact pads on an active surface of the semiconductor die. A b-stage conductive polymer is deposited over the contact pads on the semiconductor wafer. The semiconductor wafer is singulated to separate the die. An insulating layer is formed over a carrier with openings formed in the insulating layer. The die is mounted to the carrier with the conductive polymer disposed in the openings of the insulating layer. The conductive polymer is heated to a glass transition temperature to liquefy the conductive polymer to an electrically conductive state. An encapsulant is deposited over the die and insulating layer. The carrier is removed to expose the conductive polymer. An interconnect structure is formed over the die, encapsulant, and conductive polymer. The interconnect structure is electrically connected through the conductive polymer to the contact pads on the die.

A semiconductor wafer has a plurality of semiconductor die. A peripheral region is formed around the die. An insulating material is formed in the peripheral region. A portion of the insulating material is removed to form a through hole via (THV). A conductive material is deposited in the THV to form a conductive THV. A conductive layer is formed between the conductive THV and contact pads of the semiconductor die. A noise absorbing material is deposited in the peripheral region between the conductive THV to isolate the semiconductor die from intra-device interference. The noise absorbing material extends through the peripheral region from a first side of the semiconductor die to a second side of the semiconductor die. The noise absorbing material has an angular, semi-circular, or rectangular shape. The noise absorbing material can be dispersed in the peripheral region between the conductive THV.
