摘要: We have developed a novel all SU-8 packaging method for microelectromechanical system (MEMS) devices. The process is low temperature and cost it allows nonhermetic as well hermetic packaging. package can be applied to sensors. flow based on partial full exposure of negative resist using two masks. underexposed region results in cross-linking only surface layer, while the underlying not cross-linked removed developer. By depositing second layer sealed MEMS devices achieved. provides any pattern cavity clearance since solely lithography steps. concept introduced this paper then its practical validity demonstrated simulation characterization results.
