What is Photoresist Stripper?

A photoresist stripper is a solvent or chemical used to remove photoresist materials after the photolithography process. These strippers are essential for ensuring that substrates are clean and free of residues, allowing for further processing or inspection. Different formulations exist for various types of photoresists, making it critical to choose the right one for your specific material and application.

Types of Photoresist Strippers

Photoresist strippers can be categorized into two main types: organic and inorganic. Organic strippers are solvent-based and generally less aggressive but effective on positive resists. In contrast, inorganic strippers often employ strong acids or bases and are more suitable for negative resists.

Factors to Consider When Choosing

When selecting a photoresist stripper, consider the following factors:
