Publication number: 20210091032Abstract: Package structures and methods are provided for constructing multi-chip package structures using semiconductor wafer-level-fan-out techniques in conjunction with back-end-of-line fabrication methods to integrate different size chips (e.g., different thicknesses) into a planar package structure. The packaging techniques take into account intra-chip thickness variations and inter-chip thickness differences, and utilize standard back-end-of-line fabrication methods and materials to account for such thickness variations and differences. In addition, the back-end-of-line techniques allow for the formation of multiple layers of wiring and inter-layer vias which provide high density chip-to-chip interconnect wiring for high-bandwidth I/O communication between the package chips, as well as redistribution layers to route power/ground connections between active-side connections of the semiconductor chips to an area array of solder bump interconnects on a bottom side of the multi-chip package structure.Type: ApplicationFiled: September 19, 2019Publication date: March 25, 2021Inventors: Ravi K. Bonam, Mukta Ghate Farooq, Dinesh Gupta, James J. Kelly
