    Abstract: A semiconductor device has a stress relief buffer mounted to a temporary substrate in locations designated for bump formation. The stress relief buffer can be a multi-layer composite material such as a first compliant layer, a silicon layer formed over the first compliant layer, and a second compliant layer formed over the silicon layer. A semiconductor die is also mounted to the temporary substrate. The stress relief buffer can be thinner than the semiconductor die. An encapsulant is deposited between the semiconductor die and stress relief buffer. The temporary substrate is removed. An interconnect structure is formed over the semiconductor die, encapsulant, and stress relief buffer. The interconnect structure is electrically connected to the semiconductor die.

  • Patent number: 7989269
    Abstract: A semiconductor device is made by mounting a first semiconductor die to a first substrate, forming a first encapsulant over the first semiconductor die, and forming a second encapsulant over the first encapsulant. The second encapsulant is penetrable, thermally conductive material. A second semiconductor die is mounted to the second substrate. A bond wire electrically connects the second semiconductor die to the second substrate. A passive circuit element is mounted to the second substrate. Leading with the second encapsulant, the first substrate is pressed onto the second substrate so that the second encapsulant completely covers the second semiconductor die, bond wire, and passive circuit element. The second encapsulant is then cured. A third encapsulant is formed over the first and second substrates. A shield can be disposed over the second semiconductor die with openings for the second encapsulant to flow through when pressed onto the second substrate.
