Used ULTRATECH 1500 #293597692 for sale

ULTRATECH 1500 Wafer Stepper is a precision alignment and imaging equipment used in the manufacture of advanced microelectronic devices. It provides precise alignment of substrates and works in both inline and batch configurations. 1500 utilizes differential mechanisms that allow the substrate to remain stationary during alignment and imaging. This feature allows it to maintain positional accuracy over time and provide consistent results with each task. With its built-in motorized z-axis, ULTRATECH 1500 can provide repeatable and precise exposure layers for patterns. Its automated return exposure control system (RECS) ensures exposure results are in compliance with industry standards. The unit also features a dual-view capability, which allows operations to be viewed from both the top and bottom of the substrate. In addition, 1500 supports a wide range of wafer sizes, from 200- to 500-mm. Its integrated, high-precision spindle drive machine enables accurate alignments regardless of substrate size and material, up to the required masking layer. The machine is also equipped with an integrated high-speed autofocus camera, enabling it to detect out-of-plane thicknesses of less than 0.0005 mm. ULTRATECH 1500 uses low-power laser-light source metrology and is also capable of integrated in-situ particle detection. The tool also features a multilayer wafer inspection asset (MLWIS). 1500 comes with a user-friendly graphical interface that provides an intuitive method for controlling the model's various parameters and monitoring the results. This allows users to quickly set up the equipment and gain valuable testing insights. Once the system is set up, data can be exported directly to a database for later review. Overall, ULTRATECH 1500 Wafer Stepper is a powerful and versatile tool for the demanding needs of advanced microelectronic device production. Its precise alignment and imaging capabilities, combined with its automated features, offer a reliable and efficient solution for a wide range of applications.
