Webabstract = "Controlling the morphology, domain orientation, and domain size of block copolymer (BCP) thin films is desirable for many applications in nanotechnology. WebPoly(trimethylsilyl styrene-b-lactide), PTMSS -b-PLA, is silicon-substituted polymer of PS-b-PLA. PTMSS-b-PLA has higher etch selectivity and higher χ (0.34) [36] than PS-b-PLA. PTMSS-b-PLA lamella normally gives parallel orientation toward substrate, therefore, solvent anneal was applied for the patterning of perpendicular lamella [36].
