摘要:
A monomer for forming an organic anti-reflective coating layer, a polymer thereof and a composition including the same are disclosed. In a photolithography process, the organic anti-reflective coating layer absorbs an exposed light between a layer to be etched and a photoresist layer, and prevents a photoresist pattern from collapsing due to a standing wave generated under the photoresist layer. The polymer for forming an organic anti-reflective coating layer includes a repeating unit represented by Formula wherein, R1 is a hydrogen atom, a methyl group or an ethyl group, R2 is a C1˜C20 alkylene group, a C3˜C20 cycloalkylene group or a C6˜C20 aromatic hydrocarbon group, POSS is a polyhedral-oligomeric-silsesquioxane, and m is an integer of 2 to 110.

Disclosed are a photo-sensitive compound and a photoresist composition containing the same, for forming ultra-fine photoresist patterns. The photo-sensitive compound is resented by following Formula 1, wherein x is an integer of 1 to 5, y is an integer of 2 to 6, R is a C2˜C20 hydrocarbon group. The photoresist composition comprises 1˜85 weight % of a photo-sensitive compound represented by following Formula 1, 1˜55 weight % of a compound which reacts with a hydroxyl group (—OH) of the compound represented by Formula 1 to combine with the photo-sensitive compound represented by Formula 1; 1˜15 weight % of a photo-acid generator; and 12˜97 weight % of an organic solvent.
摘要:
A flowering time-controlling gene, COG2, isolated from Arabidopsis thaliana, and a protein expressed therefrom delay the flowering time of a plant and, accordingly, are useful for improving a flowering-associated character of a plant and for the identification of other flowering-associated genes or proteins.
