The Difference Between Positive and Negative Photoresist I think many people may have heard that the old metal body cameras (silver salt photos) have terms such as negative film and positive film. The photoresists used in photolithography also have negative and positive. Negative photoresist will leave a pattern where the light is irradiated, while positive photoresist will leave a pattern where the light is not irradiated. Therefore, for [...]

PSPI PSPI (photosensitive polyimide) is a very important semiconductor material, and also a very bottleneck material. What is PSPI? PSPI, the full name of which is "photosensitive polyimide", combines the excellent physical and chemical properties of polyimide (PI) with the characteristics of photosensitive materials. PSPI is similar to photoresist. Under the radiation of ultraviolet light, α rays, X-rays, etc., the structure of the irradiated part will change, and [...]
