Used USHIO UX-4240 #9402608 for sale

USHIO UX-4240 is a high-precision, computer-controlled mask aligner designed for the production of advanced integrated circuit (IC), MEMS, and sensor devices. It features ultra-high precision, high-speed alignment and high throughput for densely patterned photomasks. The unique LW-PRISM vision alignment equipment provides fast, repeatable, and precise alignment of the photomask to the workpiece. This allows for precise patterning of fine line widths and some of the most advanced lithographic applications. USHIO UX 4240 provides advanced low-coherence quadrant illumination and optional motorized lens movement to achieve precise alignment with resolution down to 0.3 micron. A high performance trinocular system enables precise viewing of the mask and any changes made to it. For precise overlay and pattern resolution, UX-4240 adopts Contact Image Sensor (CIS), Laser Image Sensor (LIS), and ImagePC image sensing systems, used together to provide precise alignment of the mask to the workpiece. The unit also offers a number of alignment and imaging options to meet the most demanding overlay requirements. UX 4240 also provides an automatic indexing machine for easy operation. It features workpiece displacement control and optical element array functions that provide the best possible control of the scattered light and beam path. In addition, the tool is equipped with a manual wafer mount holder and a 3-axis linear motorized holder for excellent alignment and sub-micron accuracy. All of these features have been designed to maximize productivity, yield, and versatility in the production of a range of advanced designs. USHIO UX-4240 also has a flexible prober upgrade option to meet the most demanding prober requirements, ensuring the highest quality of workmanship. USHIO UX 4240 is a reliable and cost-effective solution for the highest level of production requirements.
