Used ULTRATECH 1100 #9199939 for sale

ULTRATECH 1100 wafer stepper is a highly-precise, computer-controlled tool used to transfer patterns to the surface of a semiconductor wafer during its manufacture. This process is known as photolithography, and ULTRATECH makes use of projection optics, software-based controls and vacuum chucks to enable the accurate control needed to produce high-tech components from tiny silicon wafers. 1100 is capable of moving and positioning the wafer with nanometer accuracy. This level of precision means that it can be used to produce patterns with reduced line spacing. It can also be used for high-speed patterning of large wafers with smaller alignment tolerance, allowing for higher-density 3D designs. The wafer stepper contains an Advanced Projection Alignment Equipment, or APAS, which can read and compare images on both the wafer and the reticle to ensure the highest quality end-product. ULTRATECH 1100 is compatible with a variety of different reticles, including ones made from quartz, polyimide and chrome, giving it the flexibility to address a wide range of applications. 1100 also comes with a standard 12-inch large diameter wafer chucking system for holding the substrate in place during processing. This unit ensures that the wafer does not slump or contort during the archiving process. Additionally, ULTRATECH 1100 also features an automated wafer focus machine to guarantee consistent image quality across the surface. 1100 is an essential tool for modern semiconductor fabrication plants, offering incredible precision and capabilities that make it ideal for nano-scale 3D device patterning. Its sophisticated software-based controls, advanced projection alignment tool, and large 12-inch chuck offer superior results that ensure optimum yields and minimal scrap.
