Certificate of Test (or "Map")

Each piece of MCT has been issued a unique serial number which provides full traceability of raw material batches, processing and testing.

Before we ship MCT to you, we provide a Certificate of Test (COT) for each piece on your order. The COT lists many characteristics of interest to the detector designer and "maps" the composition ratio, X, and the cut-off wavelengths at 300K and 77K across the surface of the wafer. The maps are mathematically derived from scanning the wafer for IR transmission at different wavelengths and in many positions on a fixed grid.

Spitfire's COT is unique to the industry and provides a high degree of guidance on how to best process the wafer for maximum yield and performance. This is the key to fulfilling our "no surprises" promise to you.
