Abstract:
Implementations of the present disclosure relate to improved hardmask materials and methods for patterning and etching of substrates. A plurality of hardmasks may be utilized in combination with patterning and etching processes to enable advanced device architectures. In one implementation, a first hardmask and a second hardmask disposed on a substrate having various material layers disposed thereon. The second hardmask may be utilized to pattern the first hardmask during a first etching process. A third hardmask may be deposited over the first and second hardmasks and a second etching process may be utilized to form channels in the material layers.

Claim (Index 19):
A substrate processing method, comprising:\n depositing a carbonaceous hardmask on one or more oxide and nitride containing material layers disposed on a substrate; depositing a silicon containing dielectric hardmask on the carbonaceous hardmask; depositing a borocarbonitride hardmask over the one or more oxide and nitride containing material layers, the carbonaceous hardmask, and the silicon containing dielectric hardmask, the borocarbonitride hardmask comprising greater than about 25 wt % boron and about 50 wt % carbon; and etching the one or more oxide and nitride containing material layers through an opening in the borocarbonitride hardmask.
