As-Cut Silicon Substrates

As-Cut Si are wafers that are not polished. The are several steps to making a silicon wafer.

  1. As-Cut - the unpolished wafers after the ingot is sliced.
  2. Silicon Lapping
  3. Silicon Etching
  4. Silicon Polishing

As-cut wafers are much lower priced than wafers that are lapped, etched and polished. As-cut surface is extremely rough, non-reflective. Our researchers use the as-cut wafers when their research doesn't require polshed wafers. Research includes but is not limited to Solar.
