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 5):
The method of  claim 1 , wherein the carbon-containing encapsulation layer is deposited by\n introducing a silicon-containing and carbon-containing precursor; introducing a source gas in a plasma source remote from a chamber housing the substrate; generating one or more radicals of the source gas in the plasma source from the source gas; and introducing the one or more radicals of the source gas onto the substrate, wherein all or substantially all of the one or more radicals of the source gas are in a substantially low energy state that react with the silicon-containing and carbon-containing precursor to form the carbon-containing encapsulation film.
