Used NIKON i11 #293606913 for sale

NIKON i11 wafer stepper is a fully automated lithography equipment designed for semiconductor wafer processing applications. It offers highest throughput but with maximum resolution and image fidelity. The machine is ideal for production processes in a wide range of semiconductor device manufacturing. NIKON I 11 system is a powerful and reliable lithography solution for advanced photomask fabrication processes. I11 wafer stepper is powered by an advanced 22mm flat-field and 4K computer-controlled deflection unit. This machine offers highly precise photolithography processing with a large process window, which ensures high repeatability. The stepper also features a high-resolution optics tool with a large numerical aperture of 0.8 and a shutter time of only 4.5 ms. The stepper is equipped with a fully automated cleaning asset, which ensures cleanliness of the reticle and minimizes particle generation. The model also has a low-temperature view checker, allowing users to check the microscopic pattern in the reticle. This feature allows users to identify any errors or contamination before mask process start, for maximum yield and quality. I 11 wafer stepper has three stages, including a wafer stage, reticle stage and chamber stage. The wafer stage provides precise control of the scanning area of the stepper with the use of angular encoders and servo motors. It also features a standard heated chuck equipment and a resist puddle heater to ensure uniform temperature and process control. The reticle stage is equipped with an air-bearing slide to hold the mask and keep it perfectly aligned to the wafer chuck during the exposure. The chamber stage contains numerous components including a shutter, MER shield, optical window, diffuser, and Hg lamp housing. This stage ensures accurate, consistent and repeatable patterning during the wafer exposure process. NIKON i11 wafer stepper also has a user-friendly software interface that can be easily accessed from the front panel. With this interface, users can easily set up, control and monitor their production process from one central location. The stepper can also store recipe information such as exposure parameters, in order to repeat a given pattern. Overall, NIKON I 11 wafer stepper is an ideal choice for high volume wafer processing applications. It offers a high resolution optics system, automated cleaning unit, powerful deflection and scanning capabilities, user-friendly software interface and fully automatic process control. These features allow users to quickly and efficiently produce reliable and high-quality semiconductor devices.
