Instability in Si(110) etched with tetramethyl ammonium hydroxide
Experimental data for the morphological evolution of etched Si(110) is presented. The observed results are interpreted using a continuum equation. The results reveal the presence of unstable etching which leads to the formation of elliptical hollows on the surface. The early stage of the formation of hollows can be explained by a linear theory similar to that which describes the early stage of spinodal decomposition. This instability is caused by anisotropic surface tension.

Abstract

Experimental data for the morphological evolution of etched Si(110) is presented. The observed results are interpreted using a continuum equation. The results reveal the presence of unstable etching which leads to the formation of elliptical hollows on the surface. The early stage of the formation of hollows can be explained by a linear theory similar to that which describes the early stage of spinodal decomposition. This instability is caused by anisotropic surface tension.
