  • Publication number: 20100140780
    Abstract: A semiconductor device has a conductive layer formed on a substrate. The conductive layer has a first portion constituting contact pads and a second portion constituting an integrated passive device such as an inductor. A spacer is formed on the substrate around the second portion of the conductive layer. The spacer can be insulating material or conductive material for shielding. A semiconductor die is mounted to the spacer. An electrical connection is formed between contact pads on the semiconductor die and the contact pads on the substrate. An encapsulant is formed around the semiconductor die, electrical connections, spacer, and conductive layer. The substrate is removed to expose the conductive layer. An interconnect structure is formed on the backside of the substrate. The interconnect structure is electrically connected to the conductive layer.

  • Patent number: 7701040
    Abstract: A wafer level semiconductor package has a substrate and an RF module and baseband module coupled to the substrate with solder bumps. An underfill material is disposed under the RF module and baseband module. A first shielding layer is applied to a first surface of the substrate. A seed layer is deposited on the substrate and RF module and baseband module. A second shielding layer is plated over the seed layer, except over the contact pads on the substrate. The second shielding layer can be made from copper, gold, nickel, or aluminum. The first and second shielding layers substantially cover the wafer level semiconductor package to isolate the baseband module from electromagnetic interference generated by the RF module. The first and second shielding layers are grounded through the substrate.
