In this study, we propose a simple but powerful chemical wet-etching method using an HF/HNO 3 /CH 3 COOH (HNA) solution for removing the DRIE process-induced surface damage from c-Si microholes. As the HNA solution has an isotropic etching property for c-Si, the solution can etch in all directions equally regardless of the c-Si crystal orientation.
