摘要:
A method of fabricating a microarray is provided, which includes providing a substrate having a surface that is protected by an acid labile protective group that includes an acetal group represented by formula (1) and has a functional group that can be coupled with a monomer of a probe; applying a photoresist including a photo acid generator to the substrate; selectively exposing the photoresist to deprotect the acid labile protective group that corresponds to an exposed region; removing the photoresist; and coupling the monomer that is combined with the acid labile protective group with the deprotected functional group. Formula (1) has the following structure: wherein, R1 denotes an alkyl group having 1 to 5 carbon atoms, R2 denotes hydrogen or a methyl group, and Y denotes a monomer or a site coupled with the substrate.
