I would disagree that most silicon AFM probes are made using SOI. Several major probe manufacturers use a technique developed by IBM to build monolithic Si Probes. The process is detailed in the following paper: Wolter, Bayer, and Greshner "Micromachined silicon sensors for scanning force microscopy" JVST B 9 (2) Mar/Apr 1991 p.1353-1357. See also US Patent No. 5,051,379. Roger Shile -----Original Message----- Hi Dear all, I am trying to make cantilevers that can be used in AFM(Atomic Force Microscope), and silicon cantilever is one of my object. Using SOI wafer is the mostly common and simple way to achieve that, however, the expense is high. Does someone know any other method to fabricate silicon cantilevers? Any related papers? It will be very kind of you to help me. Best regards. Duan
