Mask Cleaning

Maintaining mask quality in usage is a challenge, and while photomasks are robust, they are not indestructible. The lithography processes used by our customers, regardless of sector, demand that the mask has a level of pattern integrity that enables devices to be manufactured without any imperfections, which may affect performance.

Our cleaning processes combine both chemical and physical methods. A mixture of sulphuric acid and hydrogen peroxide is used to remove photoresist and organic contaminants.

We prioritize quick turns to minimize critical delays or line-stop in fab.

Compugraphics maintains a one-of-a-kind, dedicated standalone mask cleaning & repell facility in Austin, Texas, but our US & European mask-making facilities also offer this service.
