• Silicon Wafer Processing | How Are Silicon Wafers Made?

    Because of the silicon's hardness, a diamond edge saw carefully slices the silicon wafers so they are slightly thicker than the target specification. Cleaning The final and most crucial step in the manufacturing process is polishing the wafer.

  • Edge chipping of silicon wafers in diamond grinding

    Although diamond grinding is the most commonly used machining technique in silicon wafer thinning, it often induces edge chipping which leads to wafer breakage. This study investigates edge chipping of silicon wafer in diamond grinding. The study correlates edge chipping with the crystallographic orientation and thickness of a silicon wafer

  • Silicon wafer downsizing - Sil'tronix Silicon Technologies

    Silicon wafer edge rounding. Silicon is very hard, but brittle material. The sharp edge of sawn wafers fractures readily, producing unacceptable edge chips and particles. This edge is ground with a diamond disk to remove the damage and to eliminate periferical stress. By edge grinding, the final diameter of the wafer
