WebCOP stands for Crystal Originated Particle. One of the various silicon wafer surface defects. Their basic micro structure is octahedral void shape with the size of sub-micron scale. WebThe active layer has no COP (Crystal Originated Particle or Pits) by epitaxial growth. The buried oxide is thermally grown on epitaxial Si layers and has no pinholes. We have successfully expanded the wafers to 300-mm (12-inch) diameter, in which SOI-thickness-uniformity of ±1.1% was even better than 8 inch Keywords Porous Silicon Epitaxial Layer
