Abstract

Implementations of a semiconductor package may include a semiconductor die including a first side and a second side, the first side of the semiconductor die including one or more electrical contacts; and an organic material covering at least the first side of the semiconductor die. Implementations may include where the one or more electrical contacts extend through one or more openings in the organic material; a metal-containing layer coupled to the one or more electrical contacts; and one or more slugs coupled to one of a first side of the semiconductor die, a second side of the semiconductor die, or both the first side of the semiconductor die and the second side of the semiconductor die.

Claims (10)

1. A semiconductor package, comprising:

a semiconductor die comprising a first side and a second side, the first side of the semiconductor die coupled to one or more electrical contacts;

an organic material covering at least the first side of the semiconductor die, wherein the one or more electrical contacts extend through one or more openings in the organic material;

a metal-containing layer comprised in the one or more electrical contacts; and

one or more slugs directly coupled to an outer surface of the metal-containing layer;

wherein the outer surface of the metal-containing layer is coplanar with an outermost surface of the organic material.

2. The package of claim 1 , wherein the metal-containing layer is a solder resist layer.

3. The package of claim 1 , wherein the package comprises a single slug.

4. The package of claim 1 , wherein the slug is configured to support wirebonding.

5. The package of claim 1 , wherein the organic material is directly coupled to five sides of the semiconductor die.
