Patent ID: 8148053

Claim:
A method for manufacturing a substrate for making a microarray, comprising at least the steps of: forming a monomolecular film on the surface of a substrate using a silane compound represented by the following general formula (1), Y 3 Si—(CH 2 ) m —X (1), wherein m represents an integer from 3 to 20; X represents a hydroxyl group precursor functional group which will be converted to a hydroxyl group when exposed to acid; and Y independently represents a halogen atom or an alkoxy group having 1-4 carbon atoms; and converting the hydroxyl group precursor functional group represented by X to a hydroxyl group, wherein the step of converting the hydroxyl group precursor functional group represented by X to a hydroxyl group comprises forming, on the monomolecular film, a polymer layer containing a compound represented by the following general formula (2), wherein R 1 may be the same or different, and represents a hydrogen atom, a fluorine atom, a chlorine atom, a nitro group, or a linear, branched, or cyclic alkyl group or alkoxy group having 1-12 carbon atoms substituted or unsubstituted; q independently represents 0 or 1; p is 1 or 2; r is an integer from 0 to 4; and r′ is an integer from 0 to 5; or a compound represented by the following general formula (3), wherein R 2 represents a linear, branched, or cyclic alkyl group or alkoxy group having 3-10 carbon atoms substituted or unsubstituted, or a substituted or unsubstituted phenyl group or camphor; and radiating a high energy beam onto the substrate in the form of a pattern.
