Used USHIO UX-4440 #9402609 for sale

USHIO UX-4440 is a mask aligner, developed by Japanese manufacturer USHIO, specifically designed for the production of integrated circuits. It is able to produce microcircuit structures of up to 5 micrometres by 5 micrometres resolution with a repeatability of one nanometre. USHIO UX 4440 is also capable of producing devices with feature sizes down to 0.5 micrometers. UX-4440 has a modular structure, allowing multiple stages of microprocessing to be integrated into a single platform. This makes it an ideal choice for the most advance processes, such as deep ultraviolet (DUV) and extreme ultraviolet (EUV) lithography. Additionally, UX 4440 is capable of step and repeat wafer processing, which makes it ideal for multi-bean structures in portable consumer electronics. For patterning of circuits, USHIO UX-4440 uses a step and repeat methodology. This ensures precise accuracy during the production process. To further enhance the accuracy of the system, the machine uses a "two-way" alignment system where both the mask and the wafer are moved in precise increments during the patterning process. This ensures that the mask and the wafer are perfectly aligned every time. USHIO UX 4440 also features automated control of the exposure parameters which can be set according to the desired structure of the microcircuits. Furthermore, the machine also has an exposure flatness correction system, which allows the user to adjust any misalignment in the mask to avoid any discrepancies in the patterned microcircuit. UX-4440 can process not only the usual UV lithography but also a wide range of materials including fused silica, ceramic substrates and glass. This multiple material capability increases the versatility of the mask aligner. Additionally, UX 4440 can be used as a 12-inch wafer level aligner, which is ideal for small batch production. All of these features combined make USHIO UX-4440 a powerful and versatile mask aligner for the production of integrated circuits. With its high accuracy, multi-material capabilities and automated exposure settings, USHIO UX 4440 is the perfect tool for IC production.
