AbstractIsotropic and anisotropic etching have been used in silicon processing for the past few decades. However, optimization and adaptation of anisotropic etching to standard I.C. fabrication is a more recent technology. This paper describes new methods for process and material optimization in Orientation and Concentration dependent etching of the (1 0 0) plane in silicon. Furthermore, methods of oxide and nitride pinhole detection in (1 0 0) planes in silicon are presented. New mask alignment techniques to obtain an accurate etch front termination in silicon are also shown.
