Current Situation of Lithography in China Current Situation of Lithography in China - Semiconductor Coating - Cheersonic In the process of chip production, tens of thousands of circuits need to be engraved on a small 7nm chip with optical materials, and this auxiliary optical material is photoresist. In the field of photoresist, materials are mainly divided into four types, namely g-line, i-line, KrF, ArF photoresist. short. The resolution [...]

Photoresist Classification Photoresist Classification - Spray Polyimide Photoresist - Cheersonic Photoresist, also known as photoresist, is a mixed liquid that is sensitive to light. Its components include: photoinitiators (including photosensitizers, photoacid generators), photoresist resins, monomers, solvents and other additives. The photoresist can transfer the required fine pattern from the photomask (mask) to the substrate to be processed through photochemical reaction and photolithography processes such as exposure and development. [...]

Lithography Process Summary Lithography Process Summary - Lithography Coating System - Cheersonic 1. Optical lithography is a patterning process, which uses ultraviolet light to transfer the pattern designed on the lithography or scaled lithography to the photoresist temporarily coated on the surface of the product. 2. Positive photoresist will become soluble after UV light; negative photoresist will become insoluble due to polymer crosslinking. Positive photoresists are more commonly [...]
