WebA Photoresist is an organic polymer which changes its chemical structure when exposed to ultraviolet light. Photoresists are of two types, namely, positive and negative. Positive photoresists becomes soluble when exposed to UV light, whereas negative photoresists becomes cross-linked and insoluble when exposed to UV light.
