Ultrasonic Spraying of Photoresist onto Silicon Wafer
Ultrasonic Spraying of Photoresist onto Silicon Wafer Ultrasonic spraying of photoresist onto silicon wafer may seem simple, but in fact it contains complex scientific principles. Ultrasonic spraying of photoresist is a technology widely used in semiconductor manufacturing. It sprays photoresist on silicon wafers to form fine patterns, laying the foundation for the subsequent manufacturing process. Photoresist is an organic compound, mainly composed of photosensitive resin, sensitizer and solvent. [...]
