Multi-chip package structures formed by joining chips to pre-positioned chip interconnect bridge devices

Abstract

Techniques are provided for constructing multi-chip package structures using pre-positioned interconnect bridge devices that are fabricated on a bridge wafer. For example, integrated circuit chips are mounted to a bridge wafer which is formed to have a plurality of pre-positioned interconnect bridge devices, wherein at least two integrated circuit chips are joined to each interconnect bridge device, and wherein each interconnect bridge device includes wiring to provide chip-to-chip connections between the integrated circuit chips connected to the interconnect bridge device. A wafer-level molding layer is formed on the bridge wafer to encapsulate the integrated circuit chips mounted to the bridge wafer. The interconnect bridge devices are released from the bridge wafer. The wafer-level molding layer is then diced to form a plurality of individual multi-chip modules.
