Electroless plating of copper on Si(100) surfaces modified by surface‐initiated atom‐transfer radical polymerization of 4‐vinylpyridine

Abstract

Surface-initiated atom-transfer radical polymerization (ATRP) of 4-vinylpyridine (4VP) on a pretreated Si(100) surface was carried out. The composition and topography of the Si(100) surface modified by poly(4-vinylpyridine) (P4VP) were characterized by XPS and atomic force microscopy (AFM), respectively. The P4VP layer on the Si(100) surface was used not only as chemisorption sites for the palladium complexes without prior sensitization by SnCl 2 solution during the electroless plating, but also as an adhesion promotion layer for the electrolessly deposited copper. The electrolessly deposited copper on the Si-P4VP surface exhibited a 180• peel adhesion strength above 6 N/cm. The adhesion strength was much higher than that of the electrolessly deposited copper to the pristine silicon surface.

“…38 Moreover, the ATRP of 4VP initiated from macro/nano surfaces was also reported in DMF or DMF/2-propanol mixture. 35,45 Based on these previous works, herein the ATRP on the surface of AuNR@initiator was carried out at 40 C in the presence of a CuBr/CuBr 2 /PMDETA catalytic system. [35][36][37] The relative amount of DMF, the major solvent, was maintained at 90% (v/v) to allow good dispersity of the AuNR@initiator particles, and a small amount of mixed 2-propanol/water solvent was added to provide protic solvent conditions for the ATRP reaction.…”
