What We Do

Inside every smartphone, tablet, and notebook computer

is a host of integrated circuits – the little black squares and rectangles that make up the heart, the soul, and the brain of a device. What you see is not the chip itself, but rather the black epoxy resin packaging that insulates and protects the chip inside. The chip is typically a small, thin piece of silicon containing millions of microscopic electrical components and connections.

Before these chips are packaged

wafer-diamondand integrated into your electronic device, each one is a single die on part of a much larger piece of silicon called a wafer. Building integrated circuits on the wafer surface requires hundreds of steps, many of which involve the use of light to transfer the complex circuit patterns into a photosensitive coating. This process is called photolithography, and it is one of the most critical and challenging steps in the process of manufacturing tiny integrated circuits.

But a challenge arises…

in that silicon wafers are shiny and reflect the light used to create the microscopic circuit patterns on the surface. Chip makers had to find a way to manage the reflections that bounce off the wafer during photolithography.
That’s where we come in.

Control the light. Change the world.

Brewer Science has been developing cutting-edge materials and processes for controlling light during photolithography for over three decades. Without advances such as ARC® anti-reflective coatings, electronics would not be as small, fast, or affordable as they are today.

But we didn't stop there.
