An excellent platinum piezoresistive pressure sensor using adhesive bonding with SU-8 Cheng Pang1, 2, a, Zhan Zhao 2,b, Li Shi2, Lidong Du1, 2,and Zhen Fang2, 1 State Key Laboratory of Transducer Technology, Institute of Electronics, Chinese Academy of Sciences, Beijing, CHINA 2 Graduate University of Chinese Academy of Sciences, Beijing, CHINA a pangcheng05@mails.gucas.ac.cn, b zhaozhan@mail.ie.ac.cn Keywords: Pressure sensor, Adhesive bonding, SU-8 Abstract.
Differently from the present prevailing fabrication process of silicon piezoresistive pressure sensor: platinum is used as the sensing material, with a smaller but acceptable sensitivity and much simpler processes; adhesive bonding with SU-8 is used as an alternative choice to anodic bonding, and we choose a vacuum hot plate to avoid using a bonding machine.
Differently from the present prevailing fabrication process of silicon piezoresistive pressure sensor: platinum is used as the sensing material, with a smaller but totally acceptable sensitivity and a much simpler process; adhesive bonding with SU-8 at a relatively low temperature is used as an alternative choice to anodic bonding.
