Used ULTRATECH 1500 #9390404 for sale

ULTRATECH 1500 Wafer Stepper is a machine used in the semiconductor industry for the precise and accurate transfer of patterns from a photomask or reticle to a matrix of IC's on a sensitive wafer. It's an advanced, multilayer machine with a built-in stepper control system, quartz illumination, and a stable X/Y reduction scanner. 1500 has the capability to image with features of 0.25 microns across two mask layers. ULTRATECH 1500 utilizes a quartz lamp with a collimator lens to assure accurate exposure of the wafer. The light source is calibrated to match the exact size of the photomask chip patterns and the feature sizes of the IC's. The reticle is placed in the stepper, and the wafer is fed into the stepper, where it is then scanned while the quartz lamp projects underneath. Once the scan is completed, the wafer can then be further etched and metallized to form the circuit. The stepper control system of 1500 can be configured to the best possible production speeds, minimizing product yield losses and ensuring accurate placement of the IC's. It comes with a complex set of programmable commands to automate the stepper's operation for repeatable outcomes. The illumination and collimator combination offers submicron accuracy and repeatability, while noise suppression eliminates errors from vibration. This ensures superlative registration and line width control. ULTRATECH 1500 is a versatile apparatus suitable for multiple production processes, such as printing, etching, and metallization. It has an intuitive user interface for simplified programming and operation. The stepper can be easily adjusted for higher or lower magnification and accurate reduction of the photomask reticle imaging. 1500 comes with a helping hand accessory, built-in alignment marks and cam sensors for increased alignment accuracy and repeatability. ULTRATECH 1500 is stable, reliable, and accurate, and stands out as a powerful device in the semiconductor production industry. In summary, it is an effective wafer stepper, providing superior reduction imaging, accurate and repeatable photomask pattern transfer, and enhanced throughput.
