Abstract:
Methods for forming  3 D-NAND devices comprising recessing a poly-Si layer to a depth below a spaced oxide layer. A liner is formed on the spaced oxide layer and not on the recessed poly-Si layer. A metal layer is deposited in the gaps on the liner to form wordlines.

Claim (Index 20):
A processing method comprising:\n providing a substrate surface with a plurality of spaced oxide layers with gaps between the spaced oxide layers and poly-Si layers in the gaps between the spaced oxide layers; recessing the poly-Si layer to a depth below a surface of the spaced oxide layers; forming a TiN liner on the spaced oxide layers and not on the recessed poly-Si layer, the liner having a thickness in the range of about 20 \u212b to about 50 \u212b; and depositing a tungsten layer in the gaps on the liner to form wordlines, depositing the tungsten layer comprises exposing the substrate to a tungsten precursor and a reactant, the tungsten precursor comprises one or more of WF 6 , WCl 6  or WCl 5  and the reactant comprises H 2 .
