Used ASML PAS 5500 / 100 #9218991 for sale

ASML PAS 5500 / 100 is a state-of-the-art wafer stepper built by the semiconductor equipment company ASML to enable semiconductor manufacturers to produce faster, more efficient devices. The machine has a variety of components, all of which are uniquely designed to meet the stringent demands for advanced chip production. ASML PAS 5500/100 features an aligner stage that consists of a two-axis linear actuator, a tilt actuator, a spindle, and optical encoders that measure the position of the stage with great precision. This type of precision enables the machine to automatically adjust its position on the wafer according to the microscopic details of the pattern to be printed, thus providing the most accurate possible print. The stepper also includes a wafer handling equipment that is engineered to securely transport wafers safely and accurately during the production process. This system is composed of a wafer cassette, gripper, chuck, and two loading/unloading robots which each have six padded vacuum arms. The robots and arms are controlled by a computer unit and servomotors to ensure precise movement of the wafer during transport. In addition, PAS 5500 / 100 utilizes advanced laser scanning technology to guide the exposure of ultraviolet light on the wafer in order to create microscopic lines that serve as circuit pathways. This is done by a 308 nm laser light source that emits light towards a series of mirrors and lenses to focus its illumination on very small targets on the wafer. The final key component of PAS 5500/100 is its vision machine. The vision tool utilizes two cameras, one to capture a low resolution image and the other to capture a higher resolution image. This two-camera asset enables the machine to accurately capture the detailed microscopic patterns on the wafer and is essential for the production of high-quality semiconductor devices. Overall, ASML PAS 5500 / 100 is an impressive wafer stepper that features a variety of components which work together to provide high-precision exposure of ultraviolet light on semiconductor wafers. Its advanced laser scanning, two-camera vision model, and sophisticated wafer-handling components enable it to create the most intricate and detailed microscopic patterns that are essential for the production of modern-day devices.
