  • Patent number: 10607955
    Abstract: A device may include a fan-out structure that has a plurality of integrated circuits. The integrated circuits may be of different types, such as by being configured differently or configured to perform different functions. The fan-out structure may be coupled to another integrated circuit structure, such as a die stack. For example, the fan-out structure may be coupled to a top surface or a bottom surface of the integrated circuit structure, or may otherwise be disposed within a vertical profile defined by the integrated circuit structure. Horizontally-extending and vertically-extending paths may be disposed in between and around the combined fan-out structure and integrated circuit structure to enable the integrated circuits of the two structures to communicate.

  • Patent number: 10418334
    Abstract: A semiconductor die is disclosed including corner recesses to prevent cracking of the semiconductor die during fabrication. Prior to dicing the semiconductor die from the wafer, recesses may be formed in the wafer at corners between any pair of semiconductor die. The recesses may be formed by a laser or photolithographic processes in the kerf area between semiconductor die. Once formed, the corner recesses prevent cracking and damage to semiconductor die which could otherwise occur at the corners of adjacent semiconductor die as the adjacent semiconductor die move relative to each other during the backgrind process.

  • Patent number: 10128218
    Abstract: A semiconductor device is disclosed that is formed with die bond pads at an edge of the semiconductor die. The die bond pads may be formed partially in a kerf area between semiconductor die on a wafer. When the wafer is diced, the die bond pads are severed along their length, leaving a portion of the die bond pads exposed at an edge of the diced semiconductor die. Having die bond pads at the edge of the die minimizes the offset between die when stacked into a package.
