  • Patent number: 8426252
    Abstract: In a semiconductor device package having a stress relief spacer, and a manufacturing method thereof, metal interconnect fingers extend from the body of a chip provide for chip interconnection. The metal fingers are isolated from the body of the chip by a stress-relief spacer. In one example, such isolation takes the form of an air gap. In another example, such isolation takes the form of an elastomer material. In either case, mismatch in coefficient of thermal expansion between the metal interconnect fingers and the body of the chip is avoided, alleviating the problems associated with cracking and delamination, and leading to improved device yield and device reliability.
