Package with interlocking leads and manufacturing the same

A semiconductor package formed utilizing multiple etching steps includes a lead frame, a die, and a molding compound. The lead frame includes leads and a die pad. The leads and the die pad are formed from a first conductive material by the multiple etching steps. More specifically, the leads and the die pad of the lead frame are formed by at least three etching steps. The at least three etching steps including a first etching step, a second undercut etching step, and a third backside etching step. The second undercut etching step forming interlocking portions at an end of each lead. The end of the lead is encased in the molding compound. This encasement of the end of the lead with the interlocking portion allows the interlocking portion to mechanically interlock with the molding compound to avoid lead pull out. In addition, by utilizing at least three etching steps the leads can be formed to have a height that is greater than the die pad of the lead frame. This differential in height reduces the span of wires used to form electrical connections within the semiconductor package. These reductions in the span of the wires reduces the chances of wire to wire and wire to die short circuiting because the wire sweep of the wires is reduced when the molding compound is placed.
