摘要:
Photoresist monomers which can be used to form photoresist polymers and photoresist compositions using the same which are suitable for photolithography processes employing a deep ultraviolet light source and copolymers thereof. Monomers are represented by following Formula 1: wherein, R1, is —OH or —R—OH; R represents substituted or unsubstituted linear or branched (C1-C10) alkylene, substituted or unsubstituted (C1-C10) alkylene comprising an ether linkage, substituted or unsubstituted (C1-C10) alkylene comprising an ester linkage, or substituted or unsubstituted (C1-C10) alkylene comprising an ketone moiety; and 1 is an integer of 1 or 2.

A method for making contact landing pad structures in a semiconductor integrated circuit device includes forming an isolation region and forming active regions in the semiconductor substrate. The active regions are separated by the isolation region, and each of the active regions includes one or more contact regions. The method includes forming a raised structure overlying the isolation region and disposed between a first and second contact regions. The method includes depositing a cap layer and forming an interlayer dielectric layer overlying the cap layer. The method includes depositing a photoresist layer overlying the interlayer dielectric layer and uses a mask pattern to selectively remove a portion of the photoresist layer to form a line type opening, which exposes a portion of the interlayer dielectric layer overlying at least the first and second contact regions. The method deposits a conductive fill material and performs a planarization process to form multiple conductive landing contact pads.
