Abstract:
1. A tape automated bonding (TAB) structure for connecting a chip having one or more perimeter I/Os to a circuit board, the TAB structure comprising: a TAB flex tape having a conductive lead pattern formed thereon, the conductive lead pattern including a plurality of leads configured to form an inner lead bond (ILB) area to connect to the one or more perimeter I/Os of the chip and an outer lead bond (OLB) area to connect to the circuit board, wherein at least one of the plurality of leads is internally routed relative to the ILB area so that the at least one lead has a contact exposed interior to the ILB portion of the TAB structure such that the at least one lead is configured to extend from a perimeter I/O of the chip inward to an electronic component mounted over the chip.
