IFM Imaging Procedure Place whipple grid on sample holder. Image 5 um square at a corner with IFM. Remove IFM head and replace with optical head. Place optical reticle on 5 um square corner Replace positioning reticle with sample.
IFM Imaging Procedure Move the sample to the desired testing location. Remove optical head and replace with IFM head. Image sample or begin force/creep profile.
Tip Placement Apparatus Z-stage X-Y Stage
