Abstract

A leadframe includes a frame, a die pad, a contact including a flank adjacent to the frame, a first tie bar between the frame and die pad, and a second tie bar between the die pad and contact. The leadframe is disposed over a carrier. A semiconductor die is disposed over the die pad. An encapsulant is deposited over the leadframe and semiconductor die including between the carrier and half-etched portions of the leadframe. A first trench is formed in the encapsulant to remove a portion of the frame and expose the flank of the contact. A conductive layer is formed over the flank by electroplating. A second trench is formed in the encapsulant through the second tie bar after forming the conductive layer.
