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 [...]

Photocatalytic Coating Materials The advanced UAM4000L ultrasonic spraying system demonstrates remarkable adaptability when it comes to small substrates. It is specifically engineered to handle the spraying of photocatalytic coating materials with great precision. These photocatalytic coating materials are formulated as low to medium viscosity solutions, which are meticulously blended mixtures comprising metals, metal oxides, and polymers. The unique combination of these components endows the coating with exceptional properties. [...]

Semiconductor Material Photoresist Semiconductor Material Photoresist - Photoresist Coating - Cheersonic Photoresist, this plays a vital role in chip manufacturing, let's take a deep look at its role and manufacturing process. First, let's start with the basic concept of photoresist. Photoresist is a special material that plays a role similar to photographic film in the chip manufacturing process. It functions as a mask to transfer tiny patterns or [...]
