Digital Etch Technique for Forming Ultra-Scaled Germanium-Tin (Ge 1−x Sn x ) Fin Structure

Abstract We developed a new digital etch process that allows precise etching of Germanium or Germanium-tin (Ge1−x Sn x ) materials. The digital etch approach consists of Ge1−x Sn x oxide formation by plasma oxidation and oxide removal in diluted hydrochloric acid at room temperature. The first step...
