Abstract:
1. A molded leadless package comprising: a lead frame pad having first and second surfaces that are opposite to each other; a semiconductor chip adhered to the first surface of the lead frame pad; a lead electrically coupled to the semiconductor chip; a molding material covering the lead frame pad, the semiconductor chip, and the lead in such a way as to expose a portion of the lead and a portion of the second surface of the lead frame pad to the outside, a step difference being formed between a surface of the molding material covering the second surface of the lead frame pad and the second surface of the lead frame pad itself; wherein the lead is exposed from the surface of the molding material covering the second surface of the lead frame pad; wherein the molding material covering a portion of the second surface of the lead frame pad and a portion of an exposed surface of the lead comprises a protrusion protruding from the second surface of the lead frame pad and the exposed surface of the lead; and wherein the protrusion fully exposes the lower surface of the lead.
