摘要: Aspects of the disclosure provide a semiconductor device and a method for fabricating the same. The method for fabricating the semiconductor device can include forming a stack of alternating first insulating layers and first sacrificial layers over a semiconductor substrate, and forming a staircase in the stack having a plurality of steps, with at least a first step of the staircase including a first sacrificial layer of the first sacrificial layers over a first insulating layer of the first insulating layers. Further, the method can include forming a recess in the first sacrificial layer, forming a second sacrificial layer in the recess, and replacing a portion of the first sacrificial layer and the second sacrificial layer with a conductive material that forms a contact pad.

摘要: A semiconductor device (150) includes a semiconductor surface having circuitry (180) with metal interconnect layers (122) over the semiconductor surface including a selected metal interconnect layer providing an interconnect trace (171) having a first and second end (171a, 171b). A top dielectric layer (119) is on the top metal interconnect layer. A redistribution layer (RDL) (123) is on the top dielectric layer. A corrosion interruption structure (CIS) (170) including the interconnect trace bridges an interrupting gap (123b) in a trace of the RDL.
