Abstract
A semiconductor structure includes a substrate having a memory device region and a logic device region, a first dielectric layer on the substrate, a plurality of memory stack structures on the first dielectric layer on the memory device region, an insulating layer conformally covering the memory stack structures and the first dielectric layer, a second dielectric layer on the insulating layer and completely filling the spaces between the memory stack structures, and a first interconnecting structure formed in the second dielectric layer on the logic device region. A top surface of the first interconnecting structure is flush with a top surface of the second dielectric layer and higher than top surfaces of the memory stack structures.
