    • An organic anti-reflective polymer having the following Formula 1, its preparation method, an anti-reflective coating composition comprising the said organic anti-reflective polymer and a preparation method of an anti-reflective coating made therefrom. The anti-reflective coating comprising the polymer eliminates standing waves caused by the optical properties of lower layers on the wafer and by the thickness changes of the photoresist, prevents back reflection and CD alteration caused by the diffracted and reflected light from such lower layers. Such advantages enable the formation of stable ultrafine patterns suitable for 64M, 256M, 1G, 4G, and 16G DRAM semiconductor devices, improves production yields and enables control of the k value. Further, it is also possible to prevent undercutting due to an unbalanced acidity after finishing the coating.
    • 具有下列通式1的有机抗反射聚合物,其制备方法,包含所述有机抗反射聚合物的抗反射涂料组合物和由其制备的抗反射涂层的制备方法。 包含该聚合物的抗反射涂层消除了由晶片上的下层的光学性能引起的驻波以及光致抗蚀剂的厚度变化,从而防止由这种较低层衍射的和反射光引起的背反射和CD变化。 这样的优点使得能够形成适合于64M,256M,1G,4G和16G DRAM半导体器件的稳定超细格局,提高了生产成本并且能够控制k值。 此外,还可以防止在涂覆完成后由于不均衡的酸度引起的底切。

    • The present disclosure relates to an organic anti-reflective coating composition and a method for forming photoresist patterns using the same. The anti-reflective coating compositions are useful for preventing reflection of a lower film layer or a substrate of a photoresist film, reducing standing waves caused by light and variations in the thickness of the photoresist itself, and increasing the uniformity of the photoresist patterns. More particularly, the present invention relates to an organic anti-reflective coating composition comprising particular organo-silicon based polymers and a method for forming photoresist patterns using the same. The organic anti-reflective coating composition can prevent excessive absorbency of an anti-reflective film formed therefrom and, thus, minimize the reflectivity of the film so that it can efficiently remove standing waves and increase the uniformity of the photoresist pattern.
    • 本公开涉及有机抗反射涂料组合物和使用其形成光致抗蚀剂图案的方法。 抗反射涂料组合物可用于防止光致抗蚀剂膜的下膜层或基材的反射,减少由光引起的驻波和光致抗蚀剂本身的厚度的变化,并且增加光致抗蚀剂图案的均匀性。 更具体地说,本发明涉及包含特定的有机硅基聚合物的有机抗反射涂料组合物以及使用其形成光致抗蚀剂图案的方法。 有机抗反射涂层组合物可以防止由其形成的抗反射膜的过度吸收,从而使膜的反射率最小化,使得其可以有效地去除驻波并增加光致抗蚀剂图案的均匀性。
