Best used with magnification – can be placed under a stereoscope or by using a head magnifier
Before starting, check the for the following using an optical Microscope:
Scriber tip: best results are achieved with a damage-free tip
Set the tilt and height of the diamond scribe (See Figure 1)
Set the tilt (default setting of -2 to -3 is acceptable)
Height of the diamond scriber tip should be set to just above the plane of the sample plate
Final position should be: one of the sharp facets positioned horizontally, in line with the scribe aligning guideline (See Figure 2)
Backside Scribing the Samples
Use vertical guide and sample slide or holders to achieve best scribe
For crystalline material, use a short scribe (set scribe stop with leading edge of sample touching scriber tip – See Figure 3); when scribing off crystal planes, you must use diamond scriber with damage-free tip and make a long scribe across the backside of entire sample
Cleaving procedure
Snapping – grab sample edge with scribe facing up with both hands – use thumb and middle fingers 10mm from scribe and bend sample away from scribe – will cleave along direction of scribe
Using CleanBreak – cleave sample using cleaving pliers – plier jaws positioned on edge of sample with scribe facing aligning mark on pliers
Cleaving over a pin – lay sample with scribe facing up over paper clip, need, fine wire or pin, pushing with fingers symmetrically on either side of scribe until sample cleaves
Cleaving using FlipScribe – use tip of FlipScribe scriber to cleave sample – place sample on top of scriber tip with scribe facing up, pushing with fingers symmetrically on either side until sample cleaves
We recommend using a stereoscope during this method to allow user to see sample during cleaving process
Cleaving small samples – use small sample pliers (single point cleave)
Holders allow the operator to secure wafers and/or samples (according to your application) securely
