The Critical Shear Stress for Slip Generation due to Scratches in

Abstract. The relationship between slip dislocations generation due to scratches on silicon wafers and oxygen concentration has been investigated by three-point bending tests at high temperatures from 973 to 1123 K. We have measured the critical shear stresses for slip initiation caused by surface scratches as the onset of dislocation motions.

Silicon Wafer

An interesting variation of the standard silicon wafer is the SOI substrate. To produce these wafers, two silicon wafers are bonded together, using silicon dioxide of approximately 1–2 μm thickness as a bond layer. One of the silicon wafers is thinned down to a thickness of 10–50 μm. The exact layer thickness will depend on the application.
