Used USHIO UX-4440 #9364543 for sale

USHIO UX-4440 is a mask-aligner designed to be extremely versatile and fast for nanofabrication applications. It has a 4"x4" alignment field that is accurate to 0.5 μm (microns) enabling it to handle many types of substrates. It is equipped with a precision, long lifetime stage and an air bearing precision stage, which allows for high resolution alignment and high throughput. It has an advanced auto-focus algorithm providing the best alignment accuracy and repeatability and fast analysis times. The machine also features a low-vibration platform for greater precision and stability. A 10W parallel UV xenon lamp is integrated for exposure and a fully temperature-controlled platform ensures reliable and repeatable exposure of the quartz masks. Its digital motion controller offers high speed operation with repeatable accuracy. The system is also equipped with several options for the user including a multiple exposure capability enabling efficient and accurate masks to be created, an alignment camera that allows for high accuracy alignment of the substrate, automatic stage calibration, and an ultra-fast vacuum chuck. The on-board PC has an intuitive graphical user interface (GUI), providing access to all of the machine's settings and functions. The machine also offers flexible pattern transfer utilities, making it suitable for more complex patterning and inspection processes. The system also comes with a library of pre-defined or customized user process parameters that can be quickly loaded and executed, which makes the system easy to use. USHIO UX 4440 is an advanced and highly accurate mask-aligner that can provide increased accuracy, repeatability and throughput in nanofabrication processes. Its flexibility and usability, combined with its imaging and alignment capabilities, make it an ideal choice for applications requiring high accuracy and reliable results.
