Custom Photomask Blanks

Drawing-based photomask blanks configured around substrate, chrome, resist and inspection requirements.

A blank configured around your process

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.

Prepare the surface for reliable pattern transfer

Start with the job the component must perform, then confirm the material and geometry that make the result repeatable.

Define the optical interface

The coating stack must suit the exposure wavelength, patterning route and inspection method that follow.

Separate component and system values

Material, coating and pattern tolerances describe the component. Exposure performance and system accuracy also depend on the instrument, process and mounting.

Keep the next process predictable

The supplied geometry, surface condition and inspection records are reviewed around the actual process instead of a generic product name.

Technical specifications

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.

Where this product is used

Common questions

Short answers to the questions that affect material choice, pattern definition and acceptance.

Can I order a blank from my own drawing?

Yes. Send the drawing revision, substrate, coating and process requirements for review.

Can a custom blank be supplied without a fixed standard?

Yes. The material and coating route can be defined around the actual exposure and pattern-transfer process.

What should I include in an inquiry?

Include dimensions, material, chrome or resist requirements, quantity, application and the acceptance criteria that matter.

Acceptance and drawing inputs

Confirm these items after the product type and core parameters are selected. They define how the finished component is manufactured, checked and documented.

Inspection and acceptance

Inspect the finished component against the approved drawing and agreed acceptance plan.

What to provide in the drawing or inquiry

  • Material and substrate format
  • Chrome and photoresist configuration
  • Dimensions, tolerances and clear aperture
  • Inspection, identification, packaging and delivery records

Send the drawing, reference artwork or preliminary specification for manufacturing and inspection review.

Selection notes

Custom 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.

Information for your inquiry

Material, outline, thickness, usable area, chromium stack, resist, edge treatment and delivery state.

Do I need finished pattern artwork to order a blank?

A blank order primarily needs substrate and film specifications. If pattern processing is also required, provide the artwork, polarity and revision.
