Used ASML PAS 5000 / 55A #9315876 for sale

ASML PAS 5000 / 55A is a wafer stepper used in the production of integrated circuits (ICs) such as DRAMs, microprocessors, and logic devices. It is a high-precision imaging equipment that uses a laser beam to transfer a pattern onto a silicon wafer. ASML PAS 5000 / 55 A consists of an optics stage, a scanning stage, and a control unit. The optics stage contains an illumination system, a beam-splitting unit, and a projection optics machine. The illumination tool is a powerful laser capable of producing an accurately-sized spot onto the wafer. The beam-splitting asset divides the light from the laser into two beams, which are then used to create a photomask pattern. The projection optics model magnifies the photomask pattern and accurately aligns it onto the wafer. The scanning stage consists of X and Y positioning stages and a rotation stage. The stages are used to move the wafer with respect to the pattern generated by the optics stage. Finally, the control unit is used to accurately control the operation of the wafer stepper. PAS 5000 / 55A is capable of printing patterns onto wafers with a resolution of 0.25um, which is far greater than the precision of conventional film techniques. This feature makes it ideal for the production of high-density ICs such as DRAMs. The equipment also has a high throughput rate, enabling it to produce hundreds of ICs within a short span of time. Additionally, the low exposure dose required by PAS 5000 / 55 A enables it to produce very fine features on a wafer without damaging it. ASML PAS 5000 / 55A is a reliable and accurate wafer stepper that is often employed for the fabrication of ICs. It offers high precision, high throughput, and low exposure dose, which make it an essential tool for the production of ultra-high density integrated circuits.
