Professor Judy, IntelliSense Corporation has developed a bulk silicon etch simulator called AnisE. With AnisE, you can layout your microstructure or import GDS II and DXF mask layout files. AnisE automatically simulates etching under different times, temperatures, and concentrations of etchant. An etch database of KOH and TMAH is provided for the user. It uses a molecular approach to etch simulation which mimics the actual etching planes with higher accuracy than the conventional etch plane approximation. AnisE provides 2D "real-time" visualization of the etched structure as the etching proceeds and a 3D visualization of the final etched structure. This 3D structure enables the user to determine etch depths and feature measurements. AnisE is capable of simulating undercutting and corner compensation. Many successful test results are available from a wide audience. For more information, please contact me.
