Wet anisotropic etching of sharp silicon cavities is a critical step in the fabrication of nanopores and scanning probe tips. This paper reports a straightforward method to reliably obtain sharp pyramidal cavities in (1 0 0) oriented silicon wafers from a relatively inaccurate mask fabricated with a
