    摘要: Methods, structures and designs for self-aligned local interconnects are provided. The method includes designing diffusion regions to be in a substrate. Some of a plurality of gates (74) are designed to be active gates and some of the plurality of gates are designed to be formed over isolation regions (180). The method includes designing the plurality of gates in a regular and repeating alignment along a same direction, and each of the plurality of gates are designed to have dielectric spacers (230). The method also includes designing a local interconnect layer (196) between or adjacent to the plurality of gates. The local interconnect layer is conductive and disposed over the substrate to allow electrical contact and interconnection with or to some of the diffusion regions (184) of the active gates. The local interconnect layer is self-aligned by the dielectric spacers of the plurality of gates.

    摘要: A chemically amplified negative resist composition is provided comprising (A) an alkali-soluble base polymer, (B) an acid generator, and (C) a nitrogen-containing compound, the base polymer (A) turning alkali insoluble under the catalysis of acid. A polymer having a fluorinated carboxylic acid onium salt on a side chain is included as the base polymer. Processing the negative resist composition by a lithography process may form a resist pattern with advantages including uniform low diffusion of acid, improved LER, and reduced substrate poisoning.

    摘要: A binary photomask blank has on a transparent substrate a light-shielding film including substrate-side and surface-side compositionally graded layers, having a thickness of 35-60 nm, and composed of a silicon base material containing a transition metal and N and/or O. The substrate-side compositionally graded layer has a thickness of 10-58.5 nm, and a N+O content of 25-40 at% at its lower surface and 10-23 at% at its upper surface. The surface-side compositionally graded layer has a thickness of 1.5-8 nm, and a N+O content of 10-45 at% at its lower surface and 45-55 at% at its upper surface.
