  • Abstract
    We propose a new buffered hydrofluoric acid (BHF) based solution without surfactants, BHF/H2O2, for Si oxide etching. The BHF/H2O2 solution is an application of the FPM (hydrofluoric acid-hydrogen peroxide mixture) technique reported by Shimono and Tsuiji (1991). By using BHF/H2O2 , low microroughness and high wettability to Si surfaces are achieved without adding any surfactants
