A photoresist is a light-sensitive material used form a patterned coating on a surface.

  • used in photolithography and photoengraving

This process is crucial in the electronics industry.

It’s the first step when coating the wafer.

Its purpose is to create a patterned mask on the wafer surface, allowing selective etching or doping of the underlying material. This enables the formation of intricate circuits and components on the semiconductor chip.

From Sam’s video, I saw that it was going through a centrifuge.
