Positive photoresists can keep their size and design as the photoresist developer solvent doesn't saturate the spots that have not been exposed to UV light. With negative resists, both the UV uncovered and unexposed provinces are permeated by the solvent, which can lead to design distortions.
<h3>What is a positive photoresist?</h3>
A positive photoresist is a kind of photoresist in which the part of the photoresist that is exposed to light evolves soluble to the photoresist developer. The unexposed portion of the photoresist stays insoluble to the photoresist creator.
There are two basic kinds of photoresists: negative and positive. Their primary distinction is how they respond to the light origin.
