  • Publication number: 20150332996
    Abstract: The present invention provides an interposer including multiple circuit designs and an uppermost circuit design disposed on the circuit designs. A maximum exposure region is defined as a maximum size which can be defined by a single shot of a lithographic scanner. The sizes of the circuit designs below the uppermost circuit design are smaller than the size of the maximum exposure region. Therefore, the circuit designs are respectively formed by only a single shot of the lithographic scanner. The uppermost circuit design has a length greater than the length of the maximum exposure region, so that the circuit design is formed by stitching two photomasks lithographically.
