Patent ID: 11973044
Assignee: SANDISK TECHNOLOGIES, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. The apparatus of claim 1, wherein:
the first semiconductor die further comprises a first interface connected to the bottom metal layer; and
the second semiconductor die further comprises:
a second interface in electrical communication with the first interface,
a second top metal layer below the second interface and above the metal transmission layer, and
a second bottom metal layer below the metal transmission layer;
the metal transmission layer is connected to the first metal interlayer segment via the first bottom metal layer, the first interface, the second interface and the second top metal layer;
a first electrical pathway exists from the first top metal layer through the first metal interlayer segment to the first bottom metal layer, to the second top metal layer via the first interface and the second interface, to the metal transmission layer, along the metal transmission layer to the electrical circuit on the second semiconductor die via the second bottom layer.
