Sub-5 nm Full Pitch Lamellar Microdomains by Chemical Transformation
Thomas P. Russell, Ph.D.
- Nanolithographic templates for nanoelectronics, storage media and separation media
- Smallest lamellar microdomains ever been achieved with block copolymers
- Simple process without the use of any additives for the solid state conversion of block copolymers from a disordered material to a microphase separated material
- Enabling the generation of ultra-high-resolution lithographic templates
This invention provides a simple method of fabricating microphase separated block copolymer thin films with ordered, sub-5 down to sub-3 nm full pitch lamellar microdomains. The method involves the use of acid vapor hydrolysis to convert two hydrophobic blocks of a block copolymer into one hydrophilic block and one hydrophobic block, resulting in self-assembly of the copolymer and its transformation in the solid state into microphase separated and ordered lamellar microdomain.
