Abstract
The main influences of KOH anisotropic etching of Si ⟨100⟩ wafers on etched surface flatness are investigated experimentally. In the Si membrane etching with Si3N4 mask, the Si3N4 etching and the sediments in KOH aqueous solution are found as the main influences. The effective method to improve surface quality is presented by the mechanism analysis
