Abstract: 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.

Abstract: 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. Protected catalysts disclosed herein allow careful control of precursor cross-linking, resulting in higher quality dielectric materials that may be formed by coating techniques.

Abstract: Embodiments of the invention include photoresist materials and methods of patterning photoresist materials. In an embodiment a photoresist material comprises a plurality of molecular glasses (MGs). In an embodiment, a glass transition temperature Tg of the photoresist material is less than an activation temperature needed to deblock blocking groups from the MGs. Embodiments include a method of patterning a photoresist material that comprises exposing the photoresist material with ultraviolet radiation. The method may also comprise, performing a first post exposure bake at a first temperature, that is less than the activation temperature needed to deblock blocking groups from the MGs, and performing a second post exposure bake at a second temperature that is approximately equal to or greater than the activation temperature needed to deblock blocking groups from the MGs.

Abstract: Photodefinable alignment layers for chemical assisted patterning and approaches for forming photodefinable alignment layers for chemical assisted patterning are described. An embodiment of the invention may include disposing a chemically amplified resist (CAR) material over a hardmask that includes a switch component. The CAR material may then be exposed to form exposed resist portions. The exposure may produces acid in the exposed portions of the CAR material that interact with the switch component to form modified regions of the hardmask material below the exposed resist portions.
