Abstract:
Methods and structures of a three-dimensional memory device are disclosed. In an example, the memory device includes a substrate, a first tier of conductor layers of a first length comprising a first plurality of conductor layers extending along a first direction over the substrate. The first direction is substantially parallel to a top surface of the substrate. In some embodiments, the memory device also includes at least one connection portion conductively connecting two or more conductor layers of the first tier, and a first metal contact via conductively shared by connected conductor layers of the first tier and connected to a first metal interconnect.

Claim (Index 18):
A memory device comprising:\n a substrate; a plurality of semiconductor channels, wherein one end portion of each of the plurality of semiconductor channels extends a direction substantially perpendicular to a top surface of the substrate; a drain region over the end portion of each of the plurality of semiconductor channels; a plurality of charge storage regions, each charge storage region being surrounded by a respective one of the plurality of semiconductor channels; a source region in the substrate; a plurality of bit lines each over a respective end portion of each of the plurality of semiconductor channels; a plurality of word lines extending along a direction substantially parallel to the top surface of the substrate and comprising an upper selective gate, a lower selective gate, and a plurality of word lines between the upper selective gate and the lower selective gate; a plurality of metal contact vias connecting to the plurality of word lines; a driver circuit above the plurality of bit lines, wherein: two or more of the plurality of word lines of substantially a same height over the substrate are conductively connected through at least one connection portion of substantially the same height; and the two or more of the plurality of word lines share a metal contact via that electrically connects to a respective metal interconnect, the metal contact via being formed on one of the two or more of the plurality of word lines.
