Used USHIO UX-4440 #293587280 for sale

USHIO UX-4440 mask aligner is a sophisticated and reliable lithography machine designed specifically for creating nanometer-scale circuits and devices. It is a tool used by researchers and engineers to create integrated circuits, membranes, and optoelectronic materials and devices. At its core, USHIO UX 4440 contains a 4-stage stepper motor and a 256 x 256 pixel patterning alignment equipment. This system rapidly moves the wafer stage in three-dimensional space with an average speed of 20-30 mm/s. The stepper motor is controlled with a controller that features user-programmable settings for fine-tuning process parameters in order to optimize it for varying conditions and substrates. The mask aligner utilizes an advanced immersion lithography unit that allows for resolutions down to 0.8 microns. This ensures precision placement and alignment of the pattern on the wafer. UX-4440 also features a built-in motorized machine for loading, aligning and exposing the mask. This allows for repeatable and reliable mask positioning, while a programmable inter-field protocol handles non-uniform images and reduces exposure variation. UX 4440 also has a 4-axis vibrating headstage that is used to further enhance accuracy and achieve nanometer repeatability. This feature also eliminates mask-slip issues and improves positional repeatability. Additionally, a 200 Hz heating circuit is included with the tool, which can be fine-tuned and adjusted to deal with issues such as creep and distortion. For safety and convenience, USHIO UX-4440 features an internal corrosion-resistant stainless chamber, an automatic safety shutoff, and a nitrogen purge asset with an adjustable pressure area for optimal mask protection. Furthermore, all components of the model are certified and exceed the EU Occupational Health and Safety standards. Finally, the easy-to-use control interface allows for the intuitive, fast, and efficient setting up of all parameters and operating conditions. This, coupled with the exceptional capabilities of USHIO UX 4440, make it an excellent choice for a range of nanofabrication and microfabrication tasks.
