    摘要: Methods for generating a nanostructure and for enhancing etch selectivity, and a nanostructure are disclosed. The invention implements a tunable etch-resistant anti-reflective (TERA) material integration scheme which gives high etch selectivity for both etching pattern transfer through the TERA layer (used as an ARC and/or hardmask) with etch selectivity to the patterned photoresist, and etching to pattern transfer through a dielectric layer of nitride. This is accomplished by oxidizing a TERA layer after etching pattern transfer through the TERA layer to form an oxidized TERA layer having chemical properties similar to oxide. The methods provide all of the advantages of the TERA material and allows for high etch selectivity (approximately 5–10:1) for etching to pattern transfer through nitride. In addition, the methodology reduces LER and allows for trimming despite reduced photoresist thickness.

    摘要: Disclosed is an in-situ process that prevents pattern collapse from occurring after they have been etched in S02-containing plasmas. The developed process involving treating the etched wafer to another plasma comprising of a chemically reducing gas such as H2. This treatment chemically reduces the hygroscopic sulfites/sulfates left on the surface after the main etch step. The lower sulfite/sulfate concentration on the wafer translates into considerably less moisture pick up and prevents high aspect ratio feature collapse.
