Classification: CPC G  H | IPC G  H

Claim 15:
16. A method of manufacturing a semiconductor device, comprising:
forming a resist layer comprising a resist composition over a substrate;
forming a pattern in the resist layer;
extending the pattern in the resist layer into the substrate,
wherein the resist composition comprises:
a solvent;
metal nanoparticles;
a first ligand attached to the metal nanoparticles,
wherein the first ligand includes C1-C7 alkyl groups or C1-C7 fluoroalkyl groups,
wherein the C1-C7 alkyl groups and C1-C7 fluoroalkyl groups are branched, unbranched, cyclic, or non-cyclic, and
wherein the C1-C7 alkyl groups or C1-C7 fluoroalkyl groups include one or more of —CF3, —SH, —S—, —P—, —PO2, —C(═O)SH, —C(═O)NH, —SO2OH, —SO2SH, —SOH, or —SO2—; and

a second ligand attached to the metal nanoparticles,
wherein the second ligand is a branched or unbranched, aliphatic or aromatic, substituted or unsubstituted carboxylic acid or sulfonic acid ligand, wherein when the second ligand is substituted with a substituent selected from one or more of a C1-C9 alkyl group, a C2-C9 alkenyl group, or a C6-C9 phenyl group, and
wherein the second ligand is a different material than the first ligand.
