Webintermediate silicon-containing hardmask layer 9. This layer also acted a BARC. Underneath the hardmask layer, a thick spin-on carbon (SOC) was used to planarize the substrate and effectively act as a pattern transfer layer. The etch rate diffe rential between the hardmask and the SOC is very large, thus allowing for pattern transfer.
