Abstract

In this paper, we report a fabrication method for the formation of microelectromechanical systems (MEMS) structures with perfectly protected edges and corners in {110}Si wafers using complementary metal oxide semiconductor (CMOS) compatible tetramethyl-ammonium hydroxide (TMAH) solution. Fabrication method includes two-steps wet etching. The second step of etching is carried out after mask inversion from silicon nitride (Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> ) to silicon dioxide (SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) by local oxidation of silicon (LOCOS) followed by nitride etching. Mask design methodology for the various shapes microstructures whose edges aligned along different directions is briefly discussed.
