ABSTRACT:
Photoresist monomers of following Formula 1, photoresist polymers thereof, and photoresist compositions containing the same. The photoresist polymers include a repeating unit comprising the photoresist monomer of Formula 1 as a comonomer and the photoresist compositions containing the same have excellent etching resistance, heat resistance and adhesiveness to a wafer, and are developable in aqueous tetramethylammonium hydroxide (TMAH) solutions. In addition, the photoresist compositions have a low light absorbance at 157 nm wavelength, and thus are suitable for a photolithography process using ultraviolet light sources such as VUV (157 nm) in fabricating a minute circuit for a high integration semiconductor device.wherein Y1, Y2, Y3, Y4, Y5, Y6, Z1, Z2and m are defined in the specification.
