Used HTG UV 3000A #9115291 for sale

HTG UV 3000A mask aligner is a device used in the semiconductor fabrication industry for creating tight alignment of mask patterns onto wafer surfaces. It is a laser-based mask aligner that uses highly focused ultraviolet (UV) light to accurately position a single mask pattern onto a single wafer. This device is used in the manufacture of integrated circuits (ICs) and other electronic devices. The equipment has a variety of features that make it suitable for a range of processes. It is capable of single- or multi-mask alignment and can be set up for alignment of one mask pattern with another, or for stereo alignments. The stepper motor and galvo systems provide high precision alignment, with an accuracy of 1.5um, and a maximum resolution of 0.3um. The system has an efficient alignment operation and has a minimum cycle time of 1.5 seconds. The unit has an integrated camera for enhanced accuracy, and uses a self-calibrating projection machine that allows for precise mask registration and alignment. The device also has a Full-field Interferometer (FFI) that provides fast, accurate, and reproducible scan monitor checks. The tool also has a laser-based pattern recognition asset for quick and accurate frame recognition. It also has the capability of performing on-the-fly pattern adjustments to ensure a precise mask alignment. UV 3000A is designed to be an all-in-one model, with everything the operator needs for qualified manufacturing processes. It has a built-in optical equipment that includes a compound microscope, a video monitor, and a joystick controller. The system is user friendly, with one-button operations for certain tasks. It also has a user-friendly CAD interface that enables quick and easy task definition and parameter setup. Overall, HTG UV 3000A is an advanced mask aligner designed for use with complex semiconductor manufacturing processes. It is an efficient and precise unit that ensures tight alignment of mask patterns and enables efficient production with quality and reliability.
