Curvature-Modulated Si Spherical Cap-Like Structure Fabricated by Multistep Ring Edge Etching
To create approximately spherical structures with curved sidewalls, this paper presents a method for building a series of decreasing slopes along the sidewall of a circular truncated cone. The multistep ring-edge etching technology of first reducing the concentric mask and then cutting the top off t...
