Organotin clusters, solutions of organotin clusters, and application to high resolution patterning |
| abstract |
Organotin clusters are described with the formula R 3 Sn 3 (O 2 CR′) 5−x (OH) 2+x (μ 3 -O) with 0≤x<2; R=branched or cycloalkyl with 1 to 31 carbon atoms; R′═H or alkyl with 1 to 20 carbon atoms. Three carboxylato ligands are bridging, and two OH ligands are bridging. The remaining two carboxylato ligands are in non-bridging configurations, and the non-bridging carboxylato ligands are exchangeable in solution. Solutions of these clusters are suitable for forming radiation sensitive coatings that can be used to pattern nanometer scale structures. The radiation sensitive coatings are particularly suitable for EUV patterning. |
