Abstract
To make MEMS structure design in a more intuitive way and to support the “function to 3D shape to mask” design flow a 3D feature based structure design framework and its corresponding key enabling techniques are presented on the basis of inverse design processes and topdown design methodologies Driven by space mapping among function and structure the feature model and its parameters are restricted with the bond graph represented simulation model which is constructed with functional components in simulation library at the systemlevel Conforming design rules the hierarchic feature information model is established and finally can be cascaded down to a group of 3D feature nodes which are all silicon fabrication oriented and defined on the top of CSG/Brep 3D solid models Surrounding this feature information model the 2D mask deducing and fabrication parameters extraction at the fabricationlevel can be performed for manufacturability checking design/fabrication conflict feedback and fabrication process sequence generation Taking a micro gapclosing actuator as an example the structure design process is demonstrated in terms of this 3D feature modeling methodologyThis project is under support of both Natural Science Foundation of China NSFC Grant No 50375118 and 5014006 and the Program for New Century Excellent Talents in University by China Ministry of Education CMOE Grant No NCET040928 The authors hereby thank them for the financial aid
