A novel microfabrication method for L10-FePt nanoparticles ultrathin films that utilizes fluoroalkylsilane monolayer patterned substrates was developed. A line-patterned high wettability contrast surface which consists of lyophobic fluoroalkylsilane and lyophilic Si-OH phases was prepared via the local photodecomposition of the fluoroalkylsilane monolayer. Due to high wetting contrast between these phases, anisotropic condensing behavior of the solution was observed. Xylene solutions of the L10-FePt nanoparticles were used to coat the patterned surface. The L10-FePt nanoparticles ultrathin films were selectively formed on the lyophilic areas.
