Abstract: A semiconductor device has a plurality of semiconductor die disposed over a carrier. An electrical interconnect, such as a stud bump, is formed over the semiconductor die. The stud bumps are trimmed to a uniform height. A substrate includes a bump over the substrate. The electrical interconnect of the semiconductor die is bonded to the bumps of the substrate while the semiconductor die is disposed over the carrier. An underfill material is deposited between the semiconductor die and substrate. Alternatively, an encapsulant is deposited over the semiconductor die and substrate using a chase mold. The bonding of stud bumps of the semiconductor die to bumps of the substrate is performed using gang reflow or thermocompression while the semiconductor die are in reconstituted wafer form and attached to the carrier to provide a high throughput of the flipchip type interconnect to the substrate.

Abstract: A semiconductor device includes a carrier with an interface layer applied over the carrier. The interface layer can include non-conductive paste or non-conductive film. A plurality of semiconductor die is mounted to the carrier and interface layer by pressing the semiconductor die to the carrier and interface layer for one second or less, and simultaneously thermal compression bonding multiple semiconductor die to the carrier and interface layer for 5-10 seconds. By pressing the semiconductor die to the interface layer for a short period of time and then simultaneously thermal compression bonding multiple semiconductor die to the interface layer for a second longer period of time, the overall throughput of die bonding increases to process more die per unit of time. An encapsulant is deposited over the semiconductor die. The carrier is removed and interconnect structure is formed over the semiconductor die and encapsulant.
