The name Reclaim sometimes strikes fear into the heart of semiconductor people and it really should not! Years ago some poor reclaim vendors used to turn out some pretty bad product that unfortunately gave reclaim wafers a bad name. Today there are many good reclaim vendors that turn out a very good product. Reclaim wafers are used prime and test wafers that have been stripped of thin films and re-polished to remove all patterns and scratches. Desert Silicon will sort your wafers for thickness and resistivity and in most cases reclaim wafers will perform as good as normal test wafers.
Of course the reclaim wafers will have the same limitations test wafers do when it comes to utilization for Thermal Oxidation and Photolithography. Remember reclaim wafers like test are not as flat and normally the resistivity spec they are sold under is very wide, generally 0-100 Ohm.cm. Reclaim wafers can be a little thinner but Desert Silicon will pull and dispose of the ones that are to thin and might cause you problems.
