Used NIKON S205 #293667241 for sale

NIKON S205 is a precision stepper used in semiconductor chip making. It is a large device, measuring 2550mm x 2800mm x 2800mm and weighing over 4,000kg. It is designed to provide highly accurate patterning of complex chips with extremely fine details. NIKON S 205 is equipped with a scan-head containing a 200mm projection lens and two individually-controlled capacitive-coupled mask stages. This allows the user to quickly and accurately pattern the chips, using high-resolution blue-light illumination and phase-shift masks. S205 can work with chips from 65nm to 250nm feature and defect repair, and is capable of working with a variety of photoresists and substrates. It incorporates an automated optical alignment system to precisely position the mask and wafer relative to each other before each exposure. S 205 is also equipped with a suite of chip-handling processes that reduce contamination and improve yield. It has an automated contamination prevention system and a wafer handling robot arm to reduce manual handling. It also has automated wafer flatness and topography measurement capabilities to ensure optimal device performance. NIKON S205 also incorporates an environmental monitoring system to ensure that all process conditions remain within pre-defined limits. This guarantees uniform results and minimizes the risk of device failure. Overall, NIKON S 205 is a versatile wafer stepper able to handle a wide range of chips with high precision and accuracy. With the various features included such as mask and wafer alignment, automated contamination prevention, and environmental monitoring, it ensures guidelines and highly accurate production of chips.
