Crystal orientation index
WebThe primary flat has a specific crystal orientation relative to the wafer surface; major flat. Secondary flat – Indicates the crystal orientation and doping of the wafer. The location of this flat varies. These links provide specific information on each orientation. 100> flat at 180 deg for n-type and 90 deg for p-type. 111> http://www.microscopyu.com/techniques/polarized-light/principles-of-birefringence
