摘要： A method of assembling semiconductor devices includes providing a structure that includes an array of conductive frame members beside an array of apertures and an array of conductive vias that are exposed at a first face and extend towards a second face. An array of semiconductor dies is positioned in the array of apertures with their active faces positioned in the first face of the structure. The assembly is encapsulated from the second face of the structure and a redistribution layer is formed on the first face of the structure and the active faces of the die. Material is removed from the back face of the encapsulated array to expose the vias at the back face for connection through a further redistribution layer formed on the back face to electronic components stacked vertically on the further redistribution layer.

摘要： A method of packaging a pressure sensor die that does not use pre-molded lead frames. Instead a lead frame array is attached to a tape and a non-conductive material is deposited on the lead frames. The non-conductive material is cured and the tape is removed. Pressure sensor dies then are attached to respective die pads of the lead frames and electrically connected to lead frame leads with bond wires. A gel is dispensed onto a top surface of the pressure sensor dies and then a lid is attached to each of the lead frames to cover the pressure sensor dies. The lead frames are singulated to form individual pressure sensor packages.

摘要： An interposer for a packaged semiconductor device is formed by applying an encapsulant to (e.g., by overmolding or applying lamination of tapes to) a perforated metal foil having vertical metal tabs that form the vertical metal vias in the interposer. A solid metal foil can be stamped using a micro-stamping tool to form the perforated foil and vertical tabs. Bump pads and/or re-distribution layer (RDL) traces are formed (e.g., using wafer fabrication processes or by applying flexible tape RDL layers) on the top and back sides of the foil to complete the manufacturing process. Such interposers can be cheaper to manufacture than conventional interposers having silicon or glass substrates with through-silicon vias (TSVs) formed using wafer fabrication processes.
