H. Camon et al., NEW TRENDS IN ATOMIC-SCALE SIMULATION OF WET CHEMICAL ETCHING OF SILICON WITH KOH, Materials science & engineering. B, Solid-state materials for advanced technology, 37(1-3), 1996, pp. 142-145
A new atomic scale model has been developed to simulate anisotropic et
ching of silicon in KOH solutions. This model is based on the influenc
e of the number of hydroxide groups attached to atoms. Etch rates and
macroscopic activation energies have been calculated and compared with
experimental data. Microscopic surface roughness has been investigate
d for <100> and <111> surface.
