Substrate processing apparatus and method

A substrate processing method and apparatus to create a sacrificial masking layer is disclosed. The layer is created by providing a first precursor selected to react with one of a radiation modified and unmodified layer portion and to not react with the other one of the radiation modified and unmodified layer portion on a substrate in a reaction chamber to selectively grow the sacrificial masking layer.

SUBSTRATE PROCESSING APPARATUS AND METHOD

Method for using post-processing methods for accelerating EUV lithography

Methods for using high-speed EUV resists including resists having additives that may be detrimental to etch chambers. Methods include using reversal materials and/or reversal techniques, as well as diffusion-limited etch-back and slimming for pattern creation and transfer. A substrate with high-speed EUV resist is lithographically patterned and developed into a patterned resist mask. An image reversal material is then over-coated on the patterned resist mask such that the image reversal material fills and covers the patterned resist mask. An upper portion of the image reversal material is removed such that top surfaces of the patterned resist mask are exposed. The patterned resist mask is removed such that the image reversal material remains resulting in a patterned image reversal material mask. Residual resist material is removed via a slimming process using an acid diffusion and subsequent development.
