Abstract
The evolution of higher order {221} and {331} crystal planes during co rner undercutting in the anisotropic etching of (100) silicon is discu ssed, and the occurrence of highly vertical (72.5 degrees) {311} plane s unique to KOH etches are demonstrated. Using a combined etching tech nique, very high aspect ratio micro-tips are formed and their distinct advantages for vacuum microelectronics and field-emission devices (FE D) are described.
