Used SANYU WB #187221 for sale

SANYU WB is a photoresist equipment designed for use in the fabrication of semiconductor devices. This system provides a means for patterning one or more layers of photoresist onto a substrate of choice, followed by a high-quality patterning step. WB unit is a spray-on or spincoating photoresist machine which is designed to allow users to quickly and easily coat a substrate with a film of photoresist. This photoresist is then exposed to ultraviolet (UV) radiation in order to harden specific areas of the film, creating a desired pattern. The tool consists of several components which work together to produce high-quality photoresist patterns on a substrate. This includes a spraying metering unit, an imaging unit, and a curing unit. The metering unit dispenses the photoresist onto the substrate, which can then be imaged using up to four different UV masks. Once the desired pattern has been imaged, the curing unit is used to cure it in place. SANYU WB asset offers several advantages over traditional photolithography methods. For instance, its spraying mechanism makes it ideal for wet applications like spin coating, since the photoresist can be evenly dispersed across the entire substrate. Additionally, its four masks allow for greater flexibility when it comes to patterning complex shapes. Finally, its curing unit ensures that the photoresist pattern is cured to the highest standards - allowing for chip yield-enhancing features. Overall, WB model is an ideal tool for rapidly patterning photoresist onto substrates for use in the fabrication of semiconductor devices. It offers quick, easy coating and a wide range of patterning capabilities, as well as high-quality curing, making it an invaluable asset to semiconductor designers.
