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.

摘要： Polymers are disclosed having the following formula 1 or 2: Polymers of the present invention can be used as an ARC material useful for submicrolithography processes using 248 nm KrF, 193 nm ArF and 157 nm F2 lasers. The polymers contain a chromophore substituent that exhibits sufficient absorbance at the wavelengths useful for the submicrolithography process. The ARC prevents back reflection of light from lower layers and the alteration of the CD by diffracted and reflected light from the lower layers. The ARC also eliminates standing waves and reflective notching due to the optical properties of lower layers on the wafer and to changes in the thickness of the photosensitive film applied thereon, thereby resulting in the stable formation of ultrafine patterns suitable for 64M, 256M, 1G, 4G and 16G DRAMs and a great improvement in the production yield.
