Abstract

A semiconductor component for electrical coupling to a substrate (230) includes: a semiconductor chip (110); a non-leaded leadframe (120) including a plurality of electrical contacts (130) located around a periphery (111) of the semiconductor chip; a first electrical conductor (140) electrically coupling together the semiconductor chip and the non-leaded leadframe; and a mold compound (210) disposed around the semiconductor chip, the first electrical conductor, and the plurality of electrical contacts. At least one electrical contact of the plurality of electrical contacts includes: a first surface (310) having a first surface area for electrically coupling to the semiconductor chip; and a second surface (320) opposite the first surface and having a second surface area for electrically coupling to the substrate, where the second surface area is larger than the first surface area.
