  • Patent number: 11862892
    Abstract: A method includes providing a substrate having substrate terminals and providing a first component having a first terminal and a second terminal. The method includes providing a clip structure having a first clip, a second clip, and a clip connector coupling the first clip to the second clip. The method includes coupling the first clip to the first terminal and a substrate terminal and coupling the second clip to another substrate terminal. The method includes encapsulating the structure and removing a portion of the clip connector. In some examples, the first portion of the clip connector includes a first portion surface, the second portion of the clip connector includes a second portion surface, and the first portion surface and the second portion surface are exposed from a top side of the encapsulant. Other examples and related structures are also disclosed herein.

  • Patent number: 11611170
    Abstract: In one example, a method of manufacturing a semiconductor device includes providing a substrate having substrate terminals and providing a component having a first component terminal and a second component terminal adjacent to a first major side of the component. The method includes providing a clip structure having a first clip, a second clip, and a clip connector coupling the first clip to the second clip. The method includes coupling the first clip to the first component terminal and a first substrate terminal and coupling the second clip to a second substrate terminal. The method includes encapsulating the component, portions of the substrate, and portions of the clip structure. the method includes removing a sacrificial portion of the clip connector while leaving a first portion of the clip connector attached to the first clip and leaving a second portion of the clip connector attached to the second clip.

  • Patent number: 8444799
    Abstract: A method for manufacturing a semiconductor device includes adhering an adhesive layer of a surface protective tape including a base material film, an intermediate layer disposed on the base material film, and the adhesive layer disposed on the intermediate layer to one surface of a semiconductor substrate; curing the intermediate layer while a flat plate is pressed against the base material film of the surface protective tape; grinding the other surface of the semiconductor substrate; curing the adhesive layer; and separating the surface protective tape from the semiconductor substrate.
