Abstract: A patch structure of an integrated circuit package comprises a core having a first side facing downwards and a second side facing upwards. A first solder resist (SR) layer is formed on the first side of the core, wherein the first SR layer comprises a first layer interconnect (FLI) and has a first set of one or more microbumps thereon to bond to one or more logic die. A second solder resist (SR) layer is formed on the second side of the core, wherein the second SR layer has a second set of one or more microbumps thereon to bond with a substrate. One or more bridge dies includes a respective sets of bumps, wherein the one or more bridge dies is disposed flipped over within the core such that the respective sets of bumps face downward and connect to the first set of one or more microbumps in the FLI.

Abstract: Multi-die packages including both photonic and electric integrated circuit (IC) die interconnected to each other through a routing structure built-up on a glass substrate. A glass preform comprising an optical waveguide may also be attached to the routing structure. A plurality of electrical IC (EIC) die may be arrayed over the routing structure along with a plurality of photonic IC (PIC). Each PIC may be coupled to an optical waveguide within the glass preform. Conductive vias may extend through the glass substrate and be further coupled with a host substrate. The host substrate may comprise glass and an optical waveguide embedded within the glass. A vertical coupler may be attached to the host substrate to optically couple the host substrate to the optical waveguide within the glass preform of the multi-die package. Many of the multi-die packages may be arrayed over a routing structure on the host substrate.
