fine grinding of silicon wafers

  • Laser Grinding of Single-Crystal Silicon Wafer for Surface

    In this paper we first report the laser grinding method for a single-crystal silicon wafer machined by diamond sawing. 3D laser scanning confocal microscope (LSCM) X-ray diffraction (XRD) scanning electron microscope (SEM) X-ray photoelectron spectroscopy (XPS) laser micro-Raman spectroscopy were utilized to characterize the surface quality of laser-grinded Si.

    Fine grinding with a 1200 to 2000 grit sand poligrind fine grind. This typically removes 30µm or less of material at ≤1μm/sec and provides the final finish on the wafers. A 1200 grit sand leaves a rough finish with visible grind marks while 2000 grit sand is less rough but some grind marks are still apparent.
