Abstract:
A method of processing an ultra-thin resist, comprising:depositing the ultra-thin photoresist over a semiconductor substrate, the ultra-thin resist having a thickness less than about 5,000 Ã¥; irradiating the ultra-thin resist with electromagnetic radiation having a wavelength of about 250 nm or less; developing the ultra-thin resist with a developer to form a patterned resist, the patterned resist having a surface with a first hydrophobicity; contacting the patterned resist with a transition solvent in a liquid state within about 5 minutes after developing to provide the surface of the patterned resist with a second hydrophobicity, wherein the second hydrophobicity is greater than the first hydrophobicity and contact of the patterned resist with the transition is conducted between developing the ultra-thin resist and rinsing patterned resist; and rinsing the patterned resist having the second hydrophobicity with an aqueous solution.
