Phase mask cleaning services

Ibsen offers phase mask cleaning services

Phase mask contamination can occur through residue on the fiber that is transferred onto the phase mask during the writing process, and is also dependent on care of handling as well as environment cleanliness. Effective and regular phase mask cleaning can prolong the lifetime of your phase masks.

Ibsen Phase mask shipments include a suggestion for a regular, basic cleaning process including Acetone, IPA and De-ionized water. Important tips on using this process are:

  • Use semiconductor grade chemicals, to avoid adding residue and films

  • Use new batches of chemicals every time

  • Ensure wet-to-wet processing, so that the acetone does not dry out before it is removed by the IPA

  • Spin-drying is preferred, careful blow-drying can also be used
