Used ULTRATECH 1100 #9114895 for sale

ULTRATECH 1100 is an advanced wafer stepper designed for the precision production of advanced semiconductor devices. This advanced tool provides an efficient and cost-effective way to produce high-quality lithography images. Its features help reduce wafer production time by accurately and quickly placing photolithography images onto a thin layer of photoresist. 1100 includes a smoothly contoured optical equipment with a design that optimizes image quality and improves performance. It has a field stop range from 10-12 mm, with a maximum exposure area of 8x6 inch. The system also has an automated alignment unit that ensures accurate placement of each photolithography image. It utilizes advanced telecentric optics and variable numerical aperture capability to ensure the most accurate and efficient alignment of multiple layers of photoresist. The machine also features the highest numerical aperture (NA) available on the market, reaching up to 0.575, allowing for high-resolution printing of intricate patterns and fine line shapes. This enables the production of extremely small features on the device. Additionally, the machine has quartz lens elements for even and consistent UV light exposure for the desired photoresist layer. The machine also has an advanced substrate staging machine to ensure the accuracy of the photolithography placement. It also has an integrated substrate handling tool to enable automated, unattended operation. This asset reduces time spent on setting up and positioning wafers on the machine. Furthermore, ULTRATECH 1100 has several advanced software features, such as: fully integrated process data verification, digital accelerometer to monitor shock and vibration levels, an advanced database to store and review prior jobs, wafer imaging model to preview each layer of photoresist, and assist LED lighting for improved performance. All of these features combine to make 1100 the most efficient and reliable wafer stepper currently available on the market.
