METHODS FOR PROVIDING LITHOGRAPHY FEATURES ON A SUBSTRATE BY SELF-ASSEMBLY OF BLOCK COPOLYMERS |
摘要 |
<p>A method of forming at least one lithography feature, the method comprising: providing at least one lithography recess on a substrate, the or each lithography recess comprising side-walls and a base, with the side-walls having a width therebetween; providing a self-assemblable block copolymer having first and second blocks in the or each lithography recess; causing the self-assemblable block copolymer to self-assemble into an ordered layer within the or each lithography recess, the ordered layer comprising at least a first domain of first blocks and a second domain of second blocks; causing the self-assemblable block copolymer to cross-link in a directional manner; and selectively removing the first domain to form lithography features comprised of the second domain within the or each lithography recess.</p> |
