    摘要: 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.

    摘要: Embodiments disclosed herein include a lithographic patterning system and methods of using such a system to form a microelectronic device. The lithographic patterning system includes an actinic radiation source, a stage having a surface for supporting a substrate with a resist layer, and a prism with a first surface over the stage, where the first surface has a masked layer and is substantially parallel to the surface of the stage. The prism may have a second surface that is substantially parallel to the first surface. The first and second surfaces are flat surfaces. The prism is a monolithic prism-mask, where an optical path passes through the system and exits the first surface of the prism through the mask layer. The system may include a layer disposed between the mask and resist layers. The mask layer of the prism may pattern the resist layer without an isolated mask layer.
