Used ULTRATECH 1100 #9224143 for sale

ULTRATECH 1100 is an advanced wafer stepper designed for use in photo-lithography processes. It features the ability to process a wide variety of wafers from 4" to 8" in diameter. The stepper's patented motorized head stages allow for precise positioning and repeatable alignment of the wafer for precise overlay and step/repeat imaging. 1100's vacuum-tight wafer throwing unit is engineered for maximum wafer handling accuracy, and is able to perform microstep and microdynamic movements, allowing for accurate positioning. The stepper is equipped with an exposure unit that supports exposure levels of up to 300,000 lux. This allows for a wide range of exposure times and various levels of sensitivity. ULTRATECH 1100 also features a number of workstations including a latent image monitor, reticle assembly, mechanical shutter for halo reduction, helium flow calibrator, and a gas dispersion unit for controlling fine particles. The system also includes a precision wafer alignment stage capable of sub-micron positioning accuracy. This feature allows for overlay control in the x and y axis to ensure consistent overlay and proper patterning. 1100 is capable of up to 16,000 steps using a 24" mask. ULTRATECH 1100 is an exceptionally flexible and reliable wafer stepper for production applications. It offers fast cycle times and precision accuracy even at high exposure levels. Its motorized head stages allow for precise positioning, and its advanced metrology and inspection systems guarantee critical accuracy. Furthermore, each step/repeat cycle is monitored and validated, guaranteeing consistent performance with every use. 1100 provides reliable performance, flexibility and fast cycle times for a range of production requirements.
