The method of testing semiconductor hetero-epilayer using X-ray wide angle goniometer and double crystal goniometer was introduced.Two difficulties have been surmounted in this method.They are rectifing the orientation deviation of wafer and returning to normal position of θ=0° of wide angle goniometer.With this method satisfactory results were obtained for different kinds of epilayers.This method may be applied to test the lattice mismatch between substrate and epilayer
composition and their variation
detect the perfectness of substrate and epilayer and evaluate the superlattice structure parameter etc.
