Being in one business since the start of the superconductor substrate craze has given us the leading edge in the manufacture of these materials.  We have spent endless money, time and resources to refine our processes, offering the highest consistent quality available.

We have teamed up with a university who has recently spent large funding on state of the art analytical equipment.  We have at our resources AFM, surface profilometery, x-ray orientation to less than 1 arc minute and any other studies you may request.  All substrates are cleaned, inspected and packaged in a class (1000) cleanroom.
