HTA Photomask

HTA established in 1982 as a supplier of extremely high resolution (sub-micron imagery) mask reprints. We expanded our operations early in our growth to become a full-service manufacturer of photomasks. HTA excels in the ability to offer custom engineering solutions to extraordinary photomask requirements.

HTA's photomask business now includes a broad range of photo imaged products such as precision scales, resolution targets and micro detectors, to name a few. The size of substrates we can image upon ranges from less than 0.25 inch to over 13 inches.

A growing list of products which incorporate HTA-made devices includes the photomasks for semiconductors, thin-film and microwave circuits, biomedical and analytical devices, optical scales, flat-panel displays (FPD's), lead frames, microscope reticles, sensors, and micromachined parts and other photo-sciences.

HTA routinely produces images on chromium, iron oxide, aluminum, and other common hard-surface mask coatings. We also have expertise in imaging on photographic emulsion, for those customers who have processes that are emulsion-compatible.

HTA has the skill and resources to manufacture a finished product by several different methods - e.g. step and repeat imaging, pattern generation, camera reduction and contact printing. HTA Photomask has a reputation built on delivering high quality at the lowest cost. E-beam technology - and expense - is not always necessary when pattern generation will do the job.

Our staff enjoys new manufacturing challenges. Your most demanding engineering and R&D jobs are always welcome. Although these are usually limited in volume, we frequently develop new techniques and production skills that ultimately expand our capabilities.
