Ultrasonic Spraying Photoresist Technology

Ultrasonic Spraying Photoresist Technology – Cheersonic

Photoresist deposition technology is a technology commonly used in microelectronics manufacturing, which can be used to manufacture microelectronic components such as microprocessors, integrated circuits, and optical devices. The principle of photoresist deposition technology is to use the photosensitive properties of photoresist to coat photoresist on silicon wafers or other substrates through a photolithography machine, and then form the photoresist into the desired surface through steps such as exposure and development. The pattern is finally transferred to the substrate by etching and other processes.

Advantages of ultrasonic spraying:

1. Reduce material waste and reduce costs. The preparation and processing process of photoresist is relatively complicated, so the cost of photoresist is relatively expensive, and traditional two-fluid spraying is easy to cause splashing and rebound, resulting in waste of materials. Ultrasonic spraying uses ultrasonic vibration to atomize it into fine particles and make them fall on the surface of the substrate, which greatly reduces the waste of materials,

2. The equipment is integrated with exhaust gas function to reduce environmental pollution. During the spraying process of photoresist, toxic gases may be volatilized. Ultrasonic spraying equipment can discharge exhaust gases in time to reduce the probability of human body inhaling toxic gases.

3. Ultrasonic atomization spraying to improve the uniformity of spraying. Using the ultrasonic atomization coating process, the coating uniformity is higher than the traditional two-fluid spraying.
