The semiconductor industry is growing at a rapid rate. As Moore’s Law drives thedemand for smaller and more efficient microelectronic devices, the need for advanced
lithographic techniques and materials becomes paramount. In order to meet this demand,
lithography has advanced from using deep ultraviolet (DUV) to extreme ultraviolet (EUV)
light for patterning chemically amplified resists (CARs). Yet, overcoming nanoscale
heterogeneities due to material stochastics remains a limiting factor in achieving high
precision patterning. Sequence-defined, bio-inspired polymers, such as polypeptoids, can be
employed to address the stochastic limitations inherent to synthetic polymers. This work
explores polypeptoids as a materials platform for understanding the effects of sequence on
patterning. Seven 10-mer polypeptoid sequences with varying architectures and terminal
groups were synthesized and purified. The materials were characterized using analytical high
performance liquid chromatography–mass spectrometry (HPLC–MS), differential scanning
calorimeter (DSC), and UV-Vis spectrophotometry. Preliminary patterning results provide
insight on the impact of monomer species and sequence on feature sizes, thereby
demonstrating the potential of these materials in the semiconductor industry.
