A stacked semiconductor device and method of manufacturing a stacked semiconductor device are described. The semiconductor device may include a reconstituted base layer having a plurality of embedded semiconductor chips. A first redistribution layer may contact the electrically conductive contacts of the embedded chips and extend beyond the boundary of one or more of the embedded chips, forming a fan-out area. Another chip may be stacked above the chips embedded in the base layer and be electrically connected to the embedded chips by a second redistribution layer. Additional layers of chips may be included in the semiconductor device.

Stress buffer layers for integrated microelectromechanical systems (MEMS) are described. For example, a semiconductor package includes a substrate having first and second surfaces, the second surface having an array of external conductive contacts. A microelectromechanical system (MEMS) component is disposed above the first surface of the substrate. A buffer layer is disposed above the MEMS component, the buffer layer having a first Young's modulus. A mold compound is disposed above the buffer layer, the mold compound having a second Young's modulus higher than the first Young's modulus.

According to various embodiments, a flip chip package structure is provided in which a redistribution layer (RDL) is disposed on a surface of both a semiconductor chip and one or more lateral extensions of the semiconductor chip surface. The lateral extensions may be made using, e.g., a reconstituted wafer to implement a fanout region lateral to one or more sides of the semiconductor chip. One or more electrical connectors such as solder bumps or copper cylinders may be applied to the RDL, and an interposer such as a PCB interposer may be connected to the electrical connectors. In this way, a relatively tight semiconductor pad pitch may be accommodated and translated to an appropriate circuit board pitch without necessarily requiring a silicon or glass interposer.
