ABSTRACT:
By using a branched long chained chain scission polymer as a photoresist for EUV and 157 nanometer applications, a relatively higher molecular weight polymer with good mechanical properties may be achieved. In addition, by using chain scission technology, line edge roughness and resolution may be improved at the same time.
