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 [...]

Polyimide and Photoresist Coatings Common applications for polyimide and photoresist coatings encompass a wide range of technologies and devices, including but certainly not limited to MEMS (micro-electromechanical systems), precision lenses for optics, microfluidic devices used in biotechnology and analytical chemistry, advanced microelectronics for integrated circuits and semiconductors, and precision filters for various industrial and scientific purposes. These coatings are essential for their ability to provide durability, insulation, and [...]

Photolithography Process Overview Photolithography Process Overview - Photoresist Coatings - Cheersonic Photolithography is the art and science of producing patterns on a substrate. Today, the term is most commonly used in semiconductor processing. Other adjectives are often used to more specifically define the technology, such as optical lithography or photolithography (using ultraviolet light to produce patterns), imprint lithography (pressing or stamping a mold into a material to produce [...]

Polyimide Application Areas Polyimide Application Areas - Polyimide Films Coating System - Cheersonic Polyimide (PI) is a type of aromatic heterocyclic polymer compound containing an imide ring (-CO-N-CO-) on the main chain. It is one of the most heat-resistant varieties of engineering plastics at present and is widely used in aviation, aerospace, microelectronics, nano, liquid crystal, laser and other fields. Downstream application areas of polyimide Due to the [...]
