    摘要: The present invention relates to organic anti-reflective coating polymers suitable for use in a semiconductor device during a photolithograhy process for forming ultrafine patterns using 193 nm ArF beam radiation, and preparation method therefor. Anti-reflective coating polymers of the present invention contain a monomer having a pendant phenyl group having high absorbency at the 193 nm wavelength. When the polymers of the present invention are used in an anti-reflective coating in a photolithography process for forming ultrafine patterns, the polymers eliminate the standing waves caused by changes in the thickness of the overlying photosensitive film, by the spectroscopic property of lower layers on wafer and by changes in CD due to diffractive and reflective light originating from the lower layers. Use of the anti-reflective coating of the present invention results in the stable formation of ultrafine patters suitable for 64M, 256M, 1G, 4G and 16G DRAM semiconductor devices and a great improvement in the production yield.The present invention also relates to anti-reflective coating compositions containing these polymers and to the anti-reflective coatings formed from these compositions, as well as preparation methods therefor.

    摘要: Photoresist compositions for a Top-surface Imaging Process by Silylation (TIPS), and a process for forming a positive pattern according to the TIPS using the same. The photoresist composition for the TIPS comprises a cross-linker of following Formula 1 or 2. A protecting group of the cross-linker and a hydroxyl group of the photoresist polymer are selectively crosslinked in the exposed region, and the residual hydroxyl group reacts to a silylating agent in the non-exposed region by silylation. Thus, the non-exposed region only remains after the dry-development, thereby forming a positive pattern. In addition, the photoresist composition of the present invention is suitable for the TIPS lithography using light sources such as ArF (193 nm), VUV (157 nm) and EUV (13 nm). wherein, R1, R2, R3, R4, R5, R6 and R7 are as defined in the specification.

    摘要: The present invention relates to organic anti-reflective coating polymers and preparation methods therefor. Anti-reflective coatings are used in a semiconductor device during photolithography processes to prevent the reflection of light from lower layers of the device, or resulting from changes in the thickness of the photoresist layer, and to eliminate the standing wave effect when ArF light is used. The present invention also relates to anti-reflective compositions and coatings containing these organic anti-reflective coating polymers, alone or in combination with certain light-absorbing compounds, and preparation methods therefor. When the polymers of the present invention are used in an anti-reflective coating in a photolithography process for forming submicro-patterns, the resultant elimination of changes in CD due to diffractive and reflective lights originating from lower layers increases the product yield in the formation of submicro-patterns during the manufacture of 64 M, 256 M, 1 G, 4 G and 16 G DRAM semiconductor devices.
