Critical dimension correction via calibrated trim dosing

Techniques herein include processes and systems by which a reproducible CD variation pattern can be mitigated or corrected to yield desirable CDs from microfabrication patterning processes, via resolution enhancement. A repeatable portion of CD variation across a set of wafers is identified, and then a correction exposure pattern is generated. A direct-write projection system exposes this correction pattern on a substrate as a component exposure, augmentation exposure, or partial exposure. A conventional mask-based photolithographic system executes a primary patterning exposure as a second or main component exposure. The two component exposures when combined enhance resolution of the patterning exposure to improve CDs on the substrate being processed without measure each wafer.

Integrated circuitry comprising an opaque material layer, such an interconnect metallization layer is first patterned with a maskless lithography to reveal an alignment feature, and is then patterned with masked lithography that aligns to the alignment feature. In some examples, the maskless lithography employs an I-line digital light processing (DLP) lithography system. In some examples the I-line DLP lithography system performs an alignment with IR illumination through a backside of a wafer. The maskless pattern may include dimensionally large windows within a frame around circuitry regions. A first etch of the opaque material layer may expose the alignment feature within the window, and a second etch of the opaque material may form IC features, such as interconnect metallization features.

REFRACTIVE INDEX CONTRAST POLYMERS AND METHODS FOR PRODUCING AND USING THE SAME

The present invention is directed to refractive index contrast (“RIC”) polymers and methods for producing and using the same. In one particular embodiment, RIC polymers of the invention can be used as waveguides. RIC polymers of the invention are produced from a monomeric mixture comprising a first monomer and a second monomer comprising an acid-labile protecting group, where a first polymer produced from the first monomer has a different refractive index compared to the refractive index of a second polymer produced from the second monomer. The base refractive index of RIC polymers can be tuned by controlling the amount of the first and the second monomers. Furthermore, the refractive index of the waveguide can be modulated by the amount of acid-labile protecting group removal.
