Patent number: 11953826Abstract: Lined photoresist structures to facilitate fabricating back end of line (BEOL) interconnects are described. In an embodiment, a hard mask has recesses formed therein, wherein liner structures are variously disposed each on a sidewall of a respective recess. Photobuckets comprising photoresist material are also variously disposed in the recesses. The liner structures variously serve as marginal buffers to mitigate possible effects of misalignment in the exposure of photoresist material to photons or an electron beam. In another embodiment, a recess has disposed therein a liner structure and a photobucket that are both formed by self-assembly of a photoresist-based block-copolymer.Type: GrantFiled: September 1, 2021Date of Patent: April 9, 2024Assignee: Intel CorporationInventors: James M.

Patent number: 11955377Abstract: Approaches based on differential hardmasks for modulation of electrobucket sensitivity for semiconductor structure fabrication, and the resulting structures, are described. In an example, a method of fabricating an interconnect structure for an integrated circuit includes forming a hardmask layer above an inter-layer dielectric (ILD) layer formed above a substrate. A plurality of dielectric spacers is formed on the hardmask layer. The hardmask layer is patterned to form a plurality of first hardmask portions. A plurality of second hardmask portions is formed alternating with the first hardmask portions. A plurality of electrobuckets is formed on the alternating first and second hardmask portions and in openings between the plurality of dielectric spacers. Select ones of the plurality of electrobuckets are exposed to a lithographic exposure and removed to define a set of via locations.Type: GrantFiled: January 4, 2022Date of Patent: April 9, 2024Assignee: Intel CorporationInventors: Kevin L.

Patent number: 11406972Abstract: Catalysts for facilitating cross-linking of liquid precursors into solid dielectric materials are disclosed. Initially, catalysts are protected, either by coordination with other compounds or by conversion to an ionic salt. Protection prevents catalysts from facilitating cross-linking unless activated. A catalyst is activated upon receiving an excitation, e.g. thermal excitation by heating. Upon receiving an excitation, protection of a catalyst dissociates, decomposes, becomes neutralized, or is otherwise transformed to allow the catalyst to facilitate cross-linking of the precursors into solid dielectric materials. Methods for fabricating dielectric materials using such protected catalysts as well as devices comprising the resulting materials are also described. Dielectric materials comprising cross-linked cyclic carbosilane units having a ring structure including C and Si may be formed in this manner.Type: GrantFiled: December 4, 2015Date of Patent: August 9, 2022Assignee: Intel CorporationInventors: James M. Blackwell, David J. Michalak, Jessica M. Torres, Marie Krysak, Jeffery D. Bielefeld
