Meaning

Liquid film photoresists are photosensitive polymers or oligomers dissolved in a solvent, forming a viscous liquid that can be spin-coated onto semiconductor wafers. When exposed to ultraviolet (UV) light through a photomask, the photoresist undergoes a chemical reaction, becoming either more soluble (positive photoresist) or less soluble (negative photoresist) in a developer solution. This differential solubility allows the selective removal of either exposed or unexposed regions of the photoresist, facilitating the transfer of the pattern onto the underlying substrate during subsequent etching or deposition processes.
