Silicon wafers of dimension 15 mm × 12 mm × 1 mm were cut from a single block of silicon. The wafers were first cleaned chemically with acetone and then cleaned by ultrasonic cleaning before laser processing. Since the surface may get oxidised during the WEDM process, energy dispersive X-ray (EDX) analysis was conducted to determine the ...
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.
