Used ULTRATECH Unity AP200 #9280624 for sale

ULTRATECH Unity AP200 Wafer Stepper is an advanced step-and-repeat lithography equipment designed for use in semiconductor fabrication. It is capable of exposing patterned images on up to 200mm wafers in a single shot. Unity AP200's lithography optics provide a high numerical aperture (NA) of NA=0.6 for more detailed images. The system is equipped with a 3.3Mega pixel digital imaging camera that offers a field of view of 30 mm x 40 mm. The camera utilizes a low noise imaging sensor to deliver a dynamic image range of 14-bit depth resolution. This allows for a more accurate reproduction of images on the wafer. ULTRATECH Unity AP200's electro-mechanical components are designed with high precision and reliability. This is enabled by the unit's following features: a 6-axis motion machine for precise alignment and positioning of wafers, high precision rotation stages for rotational registration accuracy of up to 5 arc seconds, and high linear speed of up to 2500 mm/s. Unity AP200's algorithms enable exposure of complex patterns with high accuracy. They include high-threshold support patterning for non-linear scan patterns and back-end patterning to enable varying pattern types and minimum program sizes. ULTRATECH Unity AP200 also includes an external laser interferometer for automatic focus control, an integrated particle monitor for protecting the optics, and a cooling tool for reducing thermal effects on the asset's performance. In addition, the model is designed for ease of operation, with a user-friendly graphical user interface (GUI), an open architecture, and a software development kit (SDK). These features ensure that users can easily program and process images for a variety of applications. Overall, Unity AP200 Wafer Stepper is an advanced, reliable lithography equipment that offers precise and accurate imaging of patterns on 200mm wafers. Its user-friendly interface, high-precision mechanical components, and robust algorithms enable the production of high-quality images for semiconductor applications.
