    Abstract: Implementations of semiconductor packages may include: a silicon die including a pad, the pad including aluminum and copper; a passivation layer over at least a portion of the silicon die and a layer of one of a polyimide (PI) a polybenzoxazole (PBO), or a polymer resin coupled to the passivation layer. The package may include a first copper layer coupled over the pad, the first copper layer being about 1 microns to about 20 microns thick; a second copper layer coupled over the first copper layer, the second copper layer may be about 5 microns to about 40 microns thick; where a width of the first copper layer above the pad may be wider than a width of the second copper layer above the pad. The first and second copper layers may be configured to bond with a heavy copper wire or solder with a copper clip.

    Abstract: In a general aspect, a method includes forming, in a semiconductor device layer disposed on a semiconductor substrate, an opening between a first semiconductor device stack included in the semiconductor device layer and a second semiconductor device stack included in the semiconductor device layer. The method also includes forming a trench in the semiconductor substrate between the first semiconductor device stack and the second semiconductor device stack, the trench corresponding with the opening. The method further includes filling the trench with a first dielectric material, thinning the semiconductor substrate to expose the first dielectric material and separate the semiconductor substrate into a first substrate portion and a second substrate portion, and forming a layer of a second dielectric material on the first substrate portion, the second substrate portion and the exposed first dielectric material.

    Abstract: A protective dam can relieve stress in a chip assembly of a high-power semiconductor device module used in electric vehicle or industrial applications. Some chip assemblies that incorporate copper spacers for thermal dissipation can cause the device module to become vulnerable to cracking. Adding a protective dam can absorb stress to prevent damage to materials surrounding the chip assembly. Various types of protective dams are presented, including high profile flexible protective dams, low profile flexible protective dams, metallic protective dams, and integral protective dams. The protective dams can be incorporated into a high-power semiconductor device module that features single sided or dual sided cooling via direct bond metal structures.

    Abstract: In a general aspect, a package includes a semiconductor die including an optical device having an optically active area on a first side of the semiconductor die. The package also includes a glass cover having an antireflective coating disposed on a central portion of a first side of the glass cover. A perimeter portion of the first side of the glass cover excludes the antireflective coating. The package further includes an adhesive resin coupling the perimeter portion of the first side of the glass cover with the first side of the semiconductor die, such that the glass cover is disposed above and spaced from the optically active area.
