Summary
| Description | Anisotropic etching of silicon in potassium hydroxide, drawn by code (hand-written SVG) to true scale (0.6 px per µm): the {111} planes meet the surface at 54.74°, so a 10 µm window at the front of a 500 µm wafer needs an opening of 10 + 2 × 500 × cot 54.74° ≈ 717 µm at the back. The membrane's thickness is exaggerated. |
