ZHANG Xu, LUO Xin-jie, HOU Zhan-qiang, et al. Sputtering process research of multilayer metal thin film in MEMS devices[J]. 2018, (1): 11-14. DOI: 10.13873/J.1000-9787(2018)01-0011-04.
Sputtering process is the main way to fabricate metal thin film of micro-electro-mechanical system(MEMS) device. Metal thin film is the mask and functional layer of MEMS device
which requires that the film has small stress
good adhesion
uniformity and weldability. By researching on characteristics of common metal thin film material
sputtering process and quality evaluation methods of multilayer metal thin film
method for process optimizing is obtained
and the quality of multilayer metal thin film is improved.
