We present experimental data for the morphological evolution of Si(110) etched with potassium hydroxide. The observed results are interpreted using a continuum equation. The results reveal the presence of unstable etching which leads to the formation of a columnar structure on the surface. The early stage of the formation of this columnar structure can be explained by a linear theory. This instability is caused by anisotropic surface tension.
