  • Title: Atomic force microscope nanolithography of polymethylmethacrylate polymer.
    Author: Teixeira FS, Mansano RD, Salvadori MC, Cattani M, Brown IG.
    Journal: Rev Sci Instrum; 2007 May; 78(5):053702. PubMed ID: 17552820.
    Abstract:
    We describe a nanolithography process for a polymethylmethacrylate (PMMA) surface using scanning contact atomic force microscopy. Parallel furrows were scribed with a pyramidal silicon tip using the same scan mechanism as used to image samples. The PMMA was first electron beam irradiated using a scanning electron microscope and developed. The topography formed is reproducible and predictable. Material from the region where the tip scribes is moved to nearby regions, and aligned, elongated PMMA fragments are seen to decorate the valleys between furrows.
