  • Publication number: 20180174831
    Abstract: Provided is a material composition and method for that includes forming a silicon-based resin over a substrate. In various embodiments, the silicon-based resin includes a nitrobenzyl functional group. In some embodiments, a baking process is performed to cross-link the silicon-based resin. Thereafter, the cross-linked silicon-based resin is patterned and an underlying layer is etched using the patterned cross-linked silicon-based resin as an etch mask. In various examples, the cross-linked silicon-based resin is exposed to a radiation source, thereby de-cross-linking the silicon-based resin. In some embodiments, the de-cross-linked silicon-based resin is removed using an organic solution.

  • Patent number: 9891528
    Abstract: A method of lithography patterning includes forming a resist layer over a substrate and providing a radiation with a first exposure dose to define an opening to be formed in the resist layer. The opening is to have a target critical dimension CD1 after developed by a negativ-tone development (NTD) process. The method further includes exposing the resist layer to the radiation with a second exposure dose less than the first exposure dose and developing the resist layer in a negative-tone development process to remove unexposed portions of the resist layer, resulting in an opening between resist patterns. A critical dimension CD2 of the opening is greater than CD1 by a delta. The method further includes forming an interfacial layer on sidewalls of the resist patterns. The interfacial layer has a thickness that is substantially equal to half of the delta.
