发明名称 Photoresist composition and patterning method thereof
摘要 Disclosed is a resist composition which has desirable physical properties such as sensitivity, resolution, residual film ratio and coating property, and forms a pattern having the desirable profile and depth of focus due to excellent light transmissivity during a semiconductor process and a flat panel display process using a short wavelength of 248 nm (KrF) or less, even though the resist composition is applied to a non-chemically amplified resist. The photoresist composition comprises a novolac-based resin A, a photosensitizer B, and a low molecular substance C having low absorbance. The low molecular substance having low absorbance has absorbance that is lower than absorbance of the novolac-based resin at one or more wavelengths of 248 nm, 193 nm, and 157 nm, and the photoresist composition is used at the wavelength of 248 nm or less.
