Overview

Photoresist is a light-sensitive material used in processes like photolithography and photoengraving to form a patterned coating on a surface. When exposed to a specific light wavelength, it undergoes chemical changes that allow selective removal of either the exposed or unexposed regions. This is critical in semiconductor and microelectronics manufacturing, as well as in creating printed circuit boards.

FAQ

What factors should I consider when purchasing photoresist?

Consider the type of photoresist (positive or negative), sensitivity to light, resolution, and compatibility with your substrate and developer.

How should photoresist be stored?

Store photoresist in a cool, dark place with a consistent temperature. It should be kept away from light and moisture to maintain its sensitivity.

What safety precautions should be taken when handling photoresist?

Wear appropriate personal protective equipment, including gloves and goggles. Ensure good ventilation and avoid direct skin contact.
