Abstract:
1. A method for manufacturing three-dimensional integrated circuits, comprising: providing an imaging writer system, wherein the imaging writer system includes a plurality of spatial light modulator (SLM) imaging units arranged in one or more parallel arrays; receiving mask data to be written to one or more layers of the three-dimensional integrated circuit; processing the mask data to form a plurality of partitioned mask data patterns corresponding to the one or more layers of the three-dimensional integrated circuit, wherein processing the mask data comprises arranging a placement of one or more layout blocks in the one or more layers of the three-dimensional integrated circuit, and identifying through silicon vias for routing communication signals between the one or more layout blocks in the one or more layers of the three-dimensional integrated circuit; assigning one or more SLM imaging units to handle each of the partitioned mask data pattern; and controlling the plurality of SLM imaging units to write the plurality of partitioned mask data patterns to the one or more layers of the three-dimensional integrated circuits in parallel.
