PHOTORESIST WITH MULTIPLE PATTERNING RADIATION-ABSORBING ELEMENTS AND/OR VERTICAL COMPOSITION GRADIENT

Various embodiments herein relate to techniques for depositing photoresist material on a substrate. For example, the tin techniques may involve providing the substrate in a reaction chamber; providing a first and second reactant to the reaction chamber, where the first reactant is an organo-metallic...

Beschreibung
Zusammenfassung:	Various embodiments herein relate to techniques for depositing photoresist material on a substrate. For example, the tin techniques may involve providing the substrate in a reaction chamber; providing a first and second reactant to the reaction chamber, where the first reactant is an organo-metallic precursor having a formula of M1aR1bL1c, where: M1 is a metal having a high patterning radiation-absorption cross-section, R1 is an organic group that survives the reaction between the first reactant and the second reactant and is cleavable from M1 under exposure to patterning radiation, L1 is a ligand, ion, or other moiety that reacts with the second reactant, a≥1, b≥1, and c≥1, and where at least one of the following conditions is satisfied: the photoresist material comprises two or more high-patterning radiation absorbing elements, and/or the photoresist material comprises a composition gradient along a thickness of the photoresist material.
