Assignee: NANYA TECHNOLOGY CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a device substrate; and
an interconnect part disposed over the device substrate, wherein the interconnect part comprises:
a lower redistribution layer electrically connected to the backside contact;
an upper redistribution layer disposed over the lower redistribution layer;
an interconnect frame disposed between and electrically connected to the lower redistribution layer and the upper redistribution layer; and
a passivation structure surrounding the interconnect frame;
a second source/drain structure disposed between the interconnect part and the device substrate;
a frontside contact disposed between the second source/drain structure and the device substrate, wherein the second source/drain structure is electrically connected to the device substrate through the frontside contact; and
a redistribution structure disposed between the backside contact and the lower redistribution layer of the interconnect part, wherein the first source/drain structure is electrically connected to the lower redistribution layer through the redistribution structure, and the second source/drain structure is electrically isolated from the redistribution structure.
