Toppan Photomasks

We may have a tremendous potential cost savings opportunity for you.



Our company has a regular supply of 6 x 6 x .250 inch and 5 x 5 x .090 inch fused silica/quartz substrates that were used once as photomasks

in the semiconductor industry. If they were to be used again, they may no longer meet the demanding specifications required for our industry.



We have found that these substrates can be re-used for many different applications.



We have re-sold these to Customers that have used them for glass wafers or other optical applications

such as windows, prisms, beam splitters, microfluidic chips, lenses and other micro optical components.



Would your company be interested in purchasing these as a potential cost savings?





Please forward this to your Purchasing department if you are not responsible for making

purchasing decisions.
