Resist

Resist is a term used in multiple fields, including chemistry, microfabrication, and art. In each of these fields, the term has a unique meaning, but generally refers to a substance or technique used to protect a certain area from an unwanted process.

Chemistry

In chemistry, a resist is a substance used to protect a part of a surface during a process, such as etching. The resist can be applied to the surface in a pattern, allowing only certain parts of the surface to be affected by the process. This technique is often used in the creation of printed circuit boards.

Microfabrication

In microfabrication, a resist is a thin layer used to transfer a circuit pattern to the substrate. This is done using a process called photolithography, where the resist is exposed to UV light. The exposed areas of the resist become soluble and can be washed away, leaving behind the desired pattern.

Art

In art, a resist is a substance applied to a surface to prevent the absorption of paint or dye. This technique is often used in batik, a method of dyeing fabric, and in watercolor painting to create highlights and textures.
