Define the optical interface
The coating stack must suit the exposure wavelength, patterning route and inspection method that follow.
Drawing-based photomask blanks configured around substrate, chrome, resist and inspection requirements.
A custom blank can start with polished glass or fused silica and include the required chrome layer, photoresist condition, optical target, edge format and inspection records. It is the right route when a standard blank does not match the drawing or exposure process.
Choose the product around the substrate, coating, pattern and exposure conditions that the finished component must support.

Start with the job the component must perform, then confirm the material and geometry that make the result repeatable.
The coating stack must suit the exposure wavelength, patterning route and inspection method that follow.
Material, coating and pattern tolerances describe the component. Exposure performance and system accuracy also depend on the instrument, process and mounting.
The supplied geometry, surface condition and inspection records are reviewed around the actual process instead of a generic product name.
Choose the supply stage that matches the processes you perform in-house: bare glass before coating, chromium-coated glass before resist coating, or a resist-coated plate before exposure.

Material, dimensions, surface, pattern, coating and documentation can be reviewed together when the standard configuration is not enough.
Material and substrate format
Chrome and photoresist configuration
Dimensions, tolerances and clear aperture
Custom plate formats and substrate/coating configurations.
Short answers to the questions that affect material choice, pattern definition and acceptance.
Yes. Send the drawing revision, substrate, coating and process requirements for review.
Yes. The material and coating route can be defined around the actual exposure and pattern-transfer process.
Include dimensions, material, chrome or resist requirements, quantity, application and the acceptance criteria that matter.
Confirm these items after the product type and core parameters are selected. They define how the finished component is manufactured, checked and documented.
Inspect the finished component against the approved drawing and agreed acceptance plan.
Send the drawing, reference artwork or preliminary specification for manufacturing and inspection review.
Discuss this productCustom photomask blanks combine a drawing-defined substrate, outline, chromium film and photoresist state.
Bare, chrome-coated and resist-coated formats serve different starting points. Match handling edges, exposure area and chemical compatibility to your equipment.
Material, outline, thickness, usable area, chromium stack, resist, edge treatment and delivery state.
A blank order primarily needs substrate and film specifications. If pattern processing is also required, provide the artwork, polarity and revision.
