Web16 feb. 2015 · If the ratio of the formation of cross-links to the scission of chains is greater than two, crosslinking takes place. These structural changes lead to a significant increase in molecular mass, reduced solubility in organic solvents and improved mechanical, thermal as well as chemical properties, which allows the use of lower-cost commodities or technical … WebMain-chain-scission-type resists have attracted much attention as the next-generation electron beam (EB) resist used for photomask fabrication.
