Used NIKON UGRMEM-01SNQ12 UTOPI-100MX #293668732 for sale

NIKON UGRMEM-01SNQ12 UTOPI-100MX Wafer Stepper is a device used in chip-making and photolithography manufacturing. Built by NIKON, this stepper is capable of accurately projecting high-resolution images onto a silicon wafer, aiding the substrate to be processed. This stepper utilizes a wafer stage, composed of an anti-reflective film, stainless-steel base, and an air-bearing equipment. This wafer stage allows for precise movement and exact alignment, a fundamental requirement in wafer processing. The photolithography process implemented with this wafer stepper begins with an electronically generated pattern, normally composed of a cad file, which is then used to generate light with a series of mirrors and optical lenses. The light is projected onto the silicon wafer and is then processed by a mixture of chemicals to form patterns or emblems. This setup enables UV light to be projected onto the substrate with high accuracy and in a timely manner so that multiple image placements can occur. UGRMEM-01SNQ12 UTOPI-100MX Wafer Stepper also incorporates an Automatic Pattern Matching System (APMS). This unit is designed to electronically recognize and accurately align the wafer pattern with the desired substrate layout, ensuring all images are correctly placed. The APMS machine also allows the user to adjust the size and scale of the images. To further ensure accuracy and precision of the wafer processing process, this stepper includes a subpixel size measurement and a control technology which will automatically detect any misalignment and make adjustments to the light projection. This stepper also includes an optimization function which will ensure the final product meets optimum wafer quality requirements. This optimization function includes autoexposure time control, autoheight offset measurements, uniform exposure, and uniform resist profiles. All of these features aim to maximize the quality of the wafer component as well as its consistency. To ensure NIKON UGRMEM-01SNQ12 UTOPI-100MX remains consistently accurate, regular maintenance should be done on it. For this purpose the manufacturer has provided a detailed manual on how to properly maintain and operate the tool. This manual includes outlined instructions on how to maintain the wafer stage, air bearing asset, and photolithography process. Since its construction, UGRMEM-01SNQ12 UTOPI-100MX wafer stepper has become an essential tool for chip-making and photolithography production and is renowned for its accurate and repeatable pattern placement. With its incorporation of the APMS model and optimization function, users can be confident that this stepper can deliver the highest possible results with each use.
