The present invention provides a polymer compound containing a repeating unit shown by the following general formula (1). There can be provided a polymer compound usable in a negative resist composition that can achieve high resolution of 50 nm or less and small LER and cause very few defects, a negative resist composition using the polymer compound, and a patterning process using the negative resist composition.
Multiple Hydrogen/Lithium Interconversions at the Same Benzene Nucleus: Two at the Most
B3LYP levels of theory. Proton abstraction from a “naked” phenyl anion by another phenyl anion is a highly endothermal process, requiring reaction enthalpies of 112, 96, and 91 kcal/mol at rtho, meta, and para positions. 1 However, the situation changes profoundly when the phenyl anion-promoted deprotonation of phenyllithiumis examined. This time the process is exothermal at ortho andpara positions by
