Abstract:
An integrated circuit memory device, in one embodiment, includes a substrate having a plurality of bit lines. A first and second inter-level dielectric layer are successively disposed on the substrate. Each of a plurality of source lines and staggered bit line contacts extend through the first inter-level dielectric layer. Each of a plurality of source line vias and a plurality of staggered bit line vias extend through the second inter-level dielectric layer to each respective one of the plurality of source lines and the plurality of staggered bit line contacts. The source lines and staggered bit line contacts that extend through the first inter-level dielectric layer are formed together by a first set of fabrication processes. The source line vias and staggered bit line contacts that extend through the second inter-level dielectric layer are also formed together by a second set of fabrication processes.
