摘要:
The present invention provides compositions for forming an oligomer array and methods for using the same. Such a composition may include an acid stable polymer, a photoacid generator and an organic solvent and may allow for the selective attachment of oligormers at one or more desired positions on a substrate using long wavelength light.

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.
摘要:
A photoresist composition includes about 4% to about 10% by weight of a photoresist resin, about 0.1% to about 0.5% by weight of a photoacid generator having a sulfonium-salt cationic group and a sulfonium-salt anionic group containing a carboxyl group as a hydrophilic site and a remainder of a solvent. The photoresist composition may form a photoresist pattern having a uniform profile.
