Claim Text:
1. A method for fabricating an electronic device, comprising: (a) providing a chemically-amplified positive-acting photoresist relief image on a substrate; (b) applying a curable composition over the photoresist relief image to provide a composite of the photoresist and curable composition, wherein the curable composition comprises a silicon-containing component; (c) treating the composite to provide relief image of photoresist encased by curable composition; (d) exposing the composite to activating radiation to permit hardening of the curable composition and then development to remove the photoresist, wherein the curable composition crosslinks in presence of acid that migrates from the photoresist, wherein following removing the photoresist, the curable composition remains in a relief image of decreased pitch relative to the photoresist.
