We manufacture the highest-quality laser patterned
photomasks at the best value.

A photomask is an image-transferring tool. The photomask is comprised of a solid, transparent substrate, such as glass or fused silica, which has an opaque coating on one surface into which a microscopic pattern has been etched, leaving some regions transparent and others opaque. The opaque regions prevent mask light from passing through, while the transparent regions allow light to pass through.

The photomask is placed in proximity to another substrate, such as a silicon wafer, which has been coated with a photosensitive material called photo resist. The light travels through the photomask, exposing certain regions of the photo resist on the adjoining substrate while the opaque regions protect the photo resist from being exposed.

Are you unhappy with your current photomask provider?
We would love an opportunity to beat those prices.

We offer the following values:

Up front pricing.

No charge for rework.

Data prep included in mask.

We offer several variable photomask services:
Standard Photomask, Midrange Photomask options, Enhanced Photomask (tighter tolerances), and 9-inch Masks.
If you have any questions, please call us at 310.634.1500 and Press 2 or contact us for photomask service.

Standard Photomask Inspection Process

Standard Service photomasks are visually inspected.

Metrology tools are calibrated with relevant traceable standards.

We place a PCM (Process Control Monitor) on the photomask. The PCM is used to measure and guarantee the features on your mask.

We can measure up to 5 specific features of your choice. Please provide a screen shot or PDF of the features to be measured.
