Patent ID: 8067271

Claim:
A method of making an integrated circuit package system comprising: forming an external interconnect, a paddle, and a tie bar, the external interconnect having a lead tip and a leadbody with a paddle top surface of the paddle below a lead top surface planar across extents of the lead tip, and a paddle bottom surface in a same horizontal plane as a lead bottom surface of the lead body; forming a through hole in the lead tip of the external interconnect; forming a longitudinal slot along a length-wise dimension of the tie bar; connecting an integrated circuit die and the external interconnect with a portion of the longitudinal slot under the integrated circuit die; and molding the external interconnect and the tie bar with an encapsulation through the through hole integral with a layer of the encapsulation above the through hole and a layer of the encapsulation below the through hole, the encapsulation filling the slot.
