World-Class Manufacturing

Brewer Science has put the resources and investments into manufacturing that are necessary to reach and achieve our customers’ goals. Our numerous cleanroom environments down to Class 10 help provide the cleanest and purest environments for manufacturing. Within these cleanrooms, we have built closed-loop systems utilizing state-of-the-art software for automating and monitoring our processes.

Quality Products for Quality People

The investments to our product improvements didn’t just stop at manufacturing product but continue into our quality control, quality engineering, analytical, and applications groups as well. Over the years we have improved the testing of our materials down to 1-part-per-trillion (1 ppt) and are working to achieve 1-part-per-quadrillion (1 ppq) results. To do this we use, and continue to invest in, leading edge analytical and process equipment.

Why is advanced photolithography needed?

All the amazing advances in the electronics age have been enabled by Moore’s Law. This law of continual miniaturization of integrated circuits is directly driven by the technology that determines the size and density of the patterns we can create through advanced photolithography.

What is photolithography?

Photolithography is the process of using light to transfer geometric patterns from a photomask to light-sensitive chemicals on a substrate. These patterns are what make up the electrical circuitry of every semiconductor device. This process usually consists of a series of chemical depositions, patterned exposures, and selective removals to produce the required features on the substrate layer by layer.

The Future of Advanced Lithography

Although the speed of Moore’s Law is slowing down, there is still a future for lithography within front-end chip processing. New materials will need to be able to withstand higher temperature processing to be compatible with chemical vapor deposition (CVD) layers for stacking.

Brewer Science is at this forefront of innovation for next generation materials to help continue front-end processing for the foreseeable future.
