According to an embodiment of the present disclosure, a method for manufacturing an integrated circuit (IC) device may include mounting an IC chip onto a center support structure of a leadframe. The leadframe may include: a plurality of pins extending from the center support structure; a groove running perpendicular to the individual pins of the plurality of pins around the center support structure; and a bar connecting the plurality of pins remote from the center support structure. The method may further include: bonding the IC chip to at least some of the plurality of pins; encapsulating the leadframe and bonded IC chip, including filling the groove with encapsulation compound; removing the encapsulation compound from the groove, thereby exposing at least a portion of the individual pins of the plurality of pins; plating the exposed portion of the plurality of pins; and cutting the IC package free from the bar by sawing through the encapsulated lead frame along the groove using a first saw width less than a width of the groove.
