摘要： Photoresist patterns are formed using a photoresist composition, which includes water, a negative photoresist polymer having a salt-type repeating unit, and a photoacid generator, so that a developing process can be performed not by using conventional TMAH solution but by using water. Additionally, because the main solvent of the composition is water, the disclosed photoresist composition is environment-friendly, and has a low light absorbance at 193 nm and 248 nm, which is useful in a photolithography process using a light source in a far ultraviolet region when high-integrated fine circuits of semiconductor device are manufactured.

摘要： The present invention provides a cross-linker monomer of formula 1, a photoresist polymer derived from a monomer comprising the same, and a photoresist composition comprising the photoresist polymer. The cross-linking unit of the photoresist polymer can be hydrolyzed (or degraded or broken) by an acid generated from a photoacid generator on the exposed region. It is believed that this acid degradation of the cross-linking unit increases the contrast ratio between the exposed region and the unexposed region. The photoresist composition of the present invention has improved pattern profile, enhanced adhesiveness, excellent resolution, sensitivity, durability and reproducibility. where A, B, R1, R2, R3, R4, R5, R6 and k are as defined herein.

摘要： 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 and improve the production yields. Another advantage is the ability to control the k value.
