Absolutely nothing! Well maybe something. But definitely not for modern-day communication of quality parameters associated with the manufacture of high-tech tooling such as a photomask.
At PhotomaskPORTAL, we provide product documentation such as the Certificate of Conformance on request in a variety of digital formats by eMail or FTP. We can also permanently embed these results on the photomask itself with the addition of a QR code. Scan this with a smart phone and ... Voila! Your quality documents appear on whatever device you choose to read them on. And you don't have to shred them when you're done.
Alternatively, you can use this QR code to attach any document you want to your photomask. This could be the design parameters, the design review, the design data, the SBIR application, ... you get the idea. We do this not only because it is environmentally-responsible, but also because it makes using our product easier. And that is our fundamental goal at PhotomaskPORTAL: to give researchers like you an easy path to low-cost, high-quality photomasks.
