A chemical composition includes a polymer chain having a surface anchoring group at a terminus of the polymer chain. The surface anchoring group is metal or dielectric selective and the polymer chain further includes at least one of a photo-acid generator, quencher, or a catalyst. In some embodiments, the surface anchoring group is metal selective or dielectric selective. In some embodiments, the polymer chain includes side polymer chains where the side polymer chains include polymers of photo-acid generators, quencher, or catalyst.

Chemical compositions and methods of patterning microelectronic device structures

Disclosed herein are structures and techniques utilizing directed self-assembly for microelectronic device fabrication. For example, a microelectronic structure may include a patterned region including a first conductive line and a second conductive line, wherein the second conductive line is adjacent to the first conductive line; and an unordered region having an unordered lamellar pattern, wherein the unordered region is coplanar with the patterned region.

Directed self-assembly structures and techniques

Techniques, structures, and materials related to extreme ultraviolet (EUV) lithography are discussed. Multiple patterning inclusive of first patterning a grating of parallel lines and second patterning utilizing EUV lithography to form plugs in the grating, and optional trimming of the plugs may be employed. EUV resists, surface treatments, resist additives, and optional processing inclusive of plug healing, angled etch processing, electric field enhanced post exposure bake are described, which provide improved processing reliability, feature definition, and critical dimensions.

EUV patterning methods, structures, and materials

A photoresist is disclosed. The photoresist includes a polymer with one repeating unit and an absorbing unit.

Chain scission photoresists and methods for forming chain scission photoresists

Chain scission resist compositions suitable for EUV lithography applications may include monomer functional groups that improve the kinetics and/or thermodynamics of the scission mechanism. Chain scission resists may include monomer functional groups that reduce the risk that leaving groups generated through the scission mechanism may chemically corrode processing equipment.
