Used USHIO UX-4240 #9364547 for sale

USHIO UX-4240 is a top-of-the-line mask aligner that is used for photolithography in semiconductor chip production. It is a highly accurate and reliable tool with a wide range of applications in the chip-making process. The equipment utilizes precision optics and micro-mechanical systems to accurately expose high-resolution patterns onto photosensitive surfaces. USHIO UX 4240 is mainly used for patterning integrated circuits on substrates such as silicon wafers, liquid crystal displays, and photomasks. It features a wide range of user-friendly features, including an easy-to-read digital display, a joystick control system, and a selectable wafer heating station. Its main advantages include a high alignment accuracy of up to 0.2 µm, a deep UV light source, and an infrared laser for mask inspection. The unit utilizes a three-axis positioning stage to accurately scan and expose the medium surface. The stage operates in a closed-loop, auto-focusing mode to ensure that the masks are accurately positioned and exposed. The machine is controlled by the onboard controller, which gives users access to a wide range of parameters and settings. The tool utilizes a pentaprism illuminator, which uses an ultra-high pressure mercury arc to provide a clean and stable light source. The asset is also capable of depositing thin films and other materials with a substantial uniformity. Additionally, it helps guarantee a high repeatable accuracy while addressing the shadowing effect that can occur when multiple cameras and lenses compete for the same light source. In terms of safety features, the model is designed with various safety features, such as a shutter to prevent stray light from entering the chamber, in order to protect both the material and operator from harm. Additionally, the equipment comes equipped with a system for controlling the pressure levels in the chamber to prevent damage to the equipment.
