In this work, a new fully automated geometrical modeling and meshing tool is described. It imports standard layout formats (CIF, GDSII, DXF), images (GIF, JPG), and 3D boundary representations (STL). A 3D model is then generated by simulating 3D operations (etching, deposition, insertion, etc.) specified by the process data or the user. A 3D finite element mesh with tagged boundary and volume conditions is then automatically created. The automatic generation of 3D model and mesh takes typically a couple of minutes on a current PC machine. The paper will present the geometry/meshing engines, user interfaces, and will demonstrate them on a range of microsystem applications.
