  • Publication number: 20230377896
    Abstract: Disclosed is a plasma diced die from the backside of the wafer using a back surface mask layer. The back surface mask layer remains on the backside of the die, serving as backside protection for the die. The plasma dicing may dice the wafer completely or partially. In the case of partial dicing, the partially diced wafer is expanded to singulate the wafer into individual dies by lateral force.

  • Publication number: 20220208686
    Abstract: A semiconductor device has a leadframe and a first electrical component including a first surface disposed on the leadframe. A first clip bond is disposed over a second surface of the first electrical component. The first clip bond extends vertically through the semiconductor device. The first clip bond has a vertical member, horizontal member connected to the vertical member, die contact integrated with the horizontal member, and clip foot extending from the vertical member. A second electrical component has a first surface disposed on the first clip bond. A second clip bond is disposed over a second surface of the second electrical component opposite the first surface of the second electrical component. An encapsulant is deposited around the first electrical component and first clip bond. A second electrical component is disposed over the encapsulant. The clip foot is exposed from the encapsulant.

  • Publication number: 20220208746
    Abstract: An embodiment related to a package is disclosed. The package includes a component mounted to a die attach region on a package substrate. A passive component with first and second passive component terminals is vertically attached to the package substrate. An encapsulant is disposed over the package substrate to encapsulate the package. In one embodiment, an external component is stacked above the encapsulant and is electrically coupled to the encapsulated package.
