Used ASML PAS 5500 / 750E #293809107 for sale

ASML PAS 5500 / 750E is a wafer stepper (also known as a photolithography machine) used in the production of integrated circuits. It is capable of producing objects up to 75 micron resolution - creating wiring and transistors with high accuracy and speed. PAS 5500 / 750E achieves this through a series of steps. First, a wafer is placed onto a stage and held in place with a vacuum. This stage is then horizontally or vertically aligned to the optics of the machine. Once the stage is correctly positioned, ASML PAS 5500 / 750E's arc-shaped reticle or mask is aligned with the wafer. The arc shape of the mask precisely follows the contour of the wafer, enabling it to effectively separate the transistors and transfer the patterns from the mask onto the wafer. PAS 5500 / 750E then uses a Stepper Equipment to accurately placeE the mask onto the wafer using a motorized stage and reflection illumination system. This stage can move in two directions: the theta axis rotates the mask, while the z-axis allows the mask to move up and down in order to defect different layers. ASML PAS 5500 / 750E also has a UV laser illuminator which emits a UV light to expose the wafer. This illumination is then filtered through the arc-shaped mask, allowing only certain wavelengths to pass through. This process is repeated several times, exposing each layer of the chip in order to create the circuitry needed. Finally, PAS 5500 / 750E uses an advanced software to control the entire unit and ensure that the layers are printed accurately. This software also helps to debug printing errors, in the event that there are any anomalies. Overall, ASML PAS 5500 / 750E can create highly accurate and fast integrated circuits through its combination of a mask, stepper machine, and UV laser illuminator. This makes it a powerful and essential tool for chip manufacturers and ensures the production of high-quality products.
