Abstract: A packaged semiconductor device includes a semiconductor die having a top side including a semiconductor surface layer having circuitry configured for a function coupled to bond pads, and a bottom side. A leadframe includes a die pad and leads or lead terminals on at least two sides of the die pad. At least one non-through hole for delamination prevention is in at least one of the die pad and the lead or the lead terminals. The semiconductor die is mounted by a die attach material with the bottom side down on the die pad. A mold compound provides encapsulation for the package semiconductor device except for at least a bottom side of the lead terminals or sidewalls of the package for the leads. The non-through hole is a filled hole filled with either the die attach material or the mold compound.

Abstract: One example described herein includes an integrated circuit (IC) package. The IC package includes a semiconductor die comprising an IC and an IC package enclosure that substantially encloses the semiconductor die. The IC package also includes at least one conductive metal contact. Each of the at least one conductive metal contact is coupled to the semiconductor die and comprises a planar solder surface exterior to the IC package enclosure to which the respective at least one metal contact is soldered to an external conductive metal contact. The planar solder surface includes at least one solder surface feature.

Abstract: A method includes rolling a roller with a protrusion across a lead frame to create an indent in a feature of the lead frame, attaching a die to a die attach pad of the lead frame, coupling the die with a lead, and enclosing portions of the die, the die attach pad, and portions of the lead frame feature with a molding compound. A system includes a roller with a cylindrical body and a protrusion, a chuck to engage a lead frame, and a controller to roll the roller across the lead frame to create an indent in a feature of the lead frame. An integrated circuit includes a package structure enclosing a first portion of a lead and a first portion of a die attach pad, and a rolled indent in the first portion of the lead or the die attach pad.
