  • Publication number: 20050255386
    Abstract: Increased protection of areas of a chip are provided by both a mask structure of increased robustness in regard to semiconductor manufacturing processes or which can be removed with increased selectivity and controllability in regard to underlying materials, or both. Mask structures are provided which exhibit an interface of a chemical reaction, grain or material type which can be exploited to enhance either or both types of protection. Structures of such masks include TERA material which can be converted or hydrated and selectively etched using a mixture of hydrogen fluoride and a hygroscopic acid or organic solvent, and two layer structures of similar or dissimilar materials.

  • Publication number: 20050098091
    Abstract: 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.
