Figure Lengend Snippet: FIG. 9. MPLS-generated pattern in SU-8 photoresist—film thickness: 40 m. a The pattern geometry is the same as in Fig. 6. Each block corresponds to 44 pixels, and the separation gap is 1 pixel wide. Some of the letters are lying sideways on the surface, demonstrating that an aspect ratio of 1:10 is achievable with MPLS scale bar of 100 m. b Micrograph of the same pattern as in a. Even small features like the number “7” with a linewidth of only 3.5 m corresponding to a single micromirror, the pixelation is clearly visible are reproduced in the photoresist scalebar 50 m. c Electron micrograph of the photoresist structures. Due to relatively poor surface adhesion of the photoresist the structures have partly detached from the glass surface scale bar of 10 m.
