Abstract:
Methods and apparatuses for depositing an encapsulation layer over a staircase structure during fabrication of a 3D NAND structure to prevent degradation of an oxide-oxide interface and to prevent punchthrough of a wordline are provided. The encapsulation layer is a carbon-containing conformal film deposited over a staircase structure of alternating oxide and nitride layers prior to depositing oxide over the staircase structure.

Claim (Index 10):
The method of  claim 1 , wherein the staircase comprises steps, each step comprising one oxide and one nitride layer, wherein each step comprises a pad extending outward from the edge of an adjacent overlying step having a width of about 150 nm to about 1000 nm.
