Abstract

The present invention provides a method of determining a crystallographic quality of a material located on a substrate. The method includes determining a set of crystallographic solutions for an unknown crystallographic orientation, and subsequently comparing the set of crystallographic solutions to adjacent known crystallographic orientations to determine the unknown crystallographic orientation. In a preferred embodiment, the set of crystallographic solutions may be a rank of crystallographic solutions which may represent the most probable crystallographic orientations. The rank of crystallographic solutions, in an alternative embodiment, may be represented by a vote, a fit and a confidence index.
