Used YUASA Unicorn #293806434 for sale

YUASA Unicorn is a photoresist equipment developed and produced by the Japanese manufacturer YUASA Corporation. It is one of the most popular photoresist systems across the industry, used for various applications such as wafer-level packaging and MEMS. Unicorn photoresist system consists of four parts. The first part is the photoresist material. The photoresist material used by YUASA Unicorn unit is an acrylic-based, electron beam (E-beam) positive photoresist that has high resolution and excellent etch-resistance. These characteristics make it ideal for a variety of applications, such as low-temperature etching, semiconductor device fabrication, MEMS and wafer-level packaging. The second part of the machine is the exposure unit. The exposure unit consists of Unicorn's linear-motion-controlled beam integrator, which contains a customized quartz window that can be used to reduce the intensity of E-beam radiation. This reduces pattern distortion and enables high resolution imaging. The third part of the tool is the development unit. YUASA Unicorn asset uses an advanced aqueous-based developing solution to remove the exposed photosensitive film. This solution provides excellent resolution and etch-resistance, and it also produces minimal residues. The last component of Unicorn model is the protective layer applicator. This applies a thin protective layer over the photoresist, protecting it from harmful UV radiation, physical damage, and moisture. This layer allows the photoresist to be stored and handled safely and prevents pattern distortion during processing. Overall, YUASA Unicorn photoresist equipment is an efficient and reliable solution for a wide variety of applications. Its high-resolution and excellent etch-resistance make it ideal for various applications, including semiconductor device fabrication, wafer-level packaging and MEMS. The system's advanced aqueous-based developing solution provides excellent resolution and etch-resistance and produces minimal residues, and its protective layer ensures that the photoresist can be stored and handled safely.
