Ultrasonic Spray for Photoresist There are a large variety of substrates that require the application of photoresist where conventional spin coating methods do not produce a uniform layer. The types of substrates include: wafers with various degrees of topography and micro vias, small glass lenses used for wearable devices, noncircular substrates, large panels, etc. The traditional spin coating method is often ineffective in applying a thin, uniform layer of photoresist [...]

Spray PCB Spray PCB - Wafer Level Coating - Cheersonic Ultrasonic spraying technology is regarded as an effective thin-film coating preparation process, such as photoresist coating on the surface of semiconductor circles. Compared with the traditional spin coating process, ultrasonic spraying can prepare the surface microstructure with better wrapping and more uniformity. photoresist coating. CHEERSONIC Ultrasonic's ultrasonic precision spraying system provides surface coating solutions for semiconductor photoresist coating, PCB flux [...]

What is a photolithography machine used for? What is a photolithography machine used for? Catalyst Coated Membranes - Cheersonic Mask Aligner, also known as mask alignment exposure machine, is the core equipment of the lithography process in the chip manufacturing process. The manufacturing process of a chip is extremely complex, but it can be summed up in several major steps: Preparation of silicon wafers-->Epitaxy process-->thermal oxidation-->diffusion doping-->ion implantation-->film preparation-->lithography-->etching-->process integration, [...]

Wafer Preparation Process Wafer Preparation Process - Wafer Coating Process - Cheersonic The ingot also undergoes a series of processing to form a semiconductor substrate, or wafer, that meets the requirements of semiconductor chip manufacturing. Silicon is the most important semiconductor material in integrated circuit manufacturing, and more than 90% of integrated circuit chips are fabricated on silicon wafers. The preparation process of silicon single crystal polished wafers is relatively [...]

18-inch Wafers The introduction of 18-inch wafers has slowed down, mainly due to the need for large-scale investment in the initial stage. Due to changes in wafer size, related equipment must be changed. Not only new factories need to be built, but equipment also needs to be replaced. Said the burden is not small. Once the plan fails, it may lead to a greater impact, causing various equipment manufacturers to [...]
