Does photoresist need phthalocyanine blue pigment?
Photoresist, also known as photoresist, is a photosensitive mixed liquid composed of photosensitive resin, sensitizer (see spectral sensitizer) and solvent. After the photosensitive resin is irradiated, the photo-curing reaction can occur quickly in the exposed area, which makes the physical properties of this material, especially the solubility and affinity, change obviously.
After proper solvent treatment, the soluble part is dissolved into the required image (see photoresist imaging plate-making process). Photoresist is widely used in the manufacture of printed circuits and integrated circuits, as well as in the process of printing and plate making. The process of photoresist is complex and varied.
According to its chemical reaction mechanism and development principle, it can be divided into negative glue and positive glue. It is negative glue that forms insoluble matter after illumination.
