Ultrasonic Atomization Spraying of Photoresist
Ultrasonic Atomization Spraying of Photoresist Photolithography technology refers to the technology of transferring the pattern on the mask plate to the substrate by means of photoresist (also known as photoresist) under the action of light. In the photolithography process, photoresist coating is an important technical link. The existing coating methods of photoresist mainly include spin coating method and spray method. The ultrasonic atomization spray coating method can be [...]
