Patent ID: 11862579

Abstract:
In various embodiments, the present disclosure provides semiconductor devices, packages, and methods. In one embodiment, a device includes a die pad, a lead that is spaced apart from the die pad, and an encapsulant on the die pad and the lead. A plurality of cavities extends into at least one of the die pad or the lead to a depth from a surface of the at least one of the die pad or the lead. The depth is within a range from 0.5 μm to 5 μm. The encapsulant extends into the plurality of cavities. The cavities facilitate improved adhesion between the die pad or lead and the encapsulant, as the cavities increase a surface area of contact with the encapsulant, and further increase a mechanical interlock with the encapsulant, as the cavities may have a rounded or semi-spherical shape.
