Used NIKON NSR S204 #9243689 for sale

NIKON NSR S204 is a high-performance wafer stepper designed for semiconductor fabrication. It utilizes NIKON proprietary Array Micro-Scanning (AMS) technology to deliver accurate, high throughput wafer scanning. With its high resolution, high speed operation, and comprehensive automata monitoring and control equipment, NSR S204 is an ideal solution for advanced semiconductor fabrication processes. NIKON NSR S204 is capable of shrinking down the minimum linewidths on photomasks and creating highly precise wafer patterns. This is made possible with the integrated sophisticated software for controlling, calibrating, and monitoring the writing operation. The stepper features a rugged, multi-axis micropositioning system which is stabilized by an encoder to ensure accuracy and fast scanning. Contained within an industrial-grade frame, NSR S204 is designed to withstand the tough factory environment. NIKON NSR S204 produces high-resolution images by creating an array of up to 24 million pixels per a single wafer, with no off-the-chip lag. The controller board's multi-cascaded voltage circuits enable linear and non-linear voltages to be changed in real-time, while the built-in autofocus unit ensures that the wafer surface remains perfectly aligned. The exposure machine of NSR S204 features a laser diode array which emits multicolor light based on the desired wafer pattern. By means of a computer program, the exposure controller sets specific values to each laser color. This helps create precise contact patterns at different exposure times, allowing for multiple-layer imaging and patterning. In addition to its high-precision optics, NIKON NSR S204 is equipped with Smartline, which is an intelligent wafer handling tool. Smartline employs powerful algorithms to identify each masked wafer on the platen and intelligently reposition each one during processing. This ensures that wafers are consistently exposed regardless of misalignment or sudden movement due to vibration. It also helps reduce misrecognition errors. In short, NSR S204 is an advanced, high-precision wafer stepper that offers a high throughput, integrated process controls, and an efficient wafer handling asset. It is the perfect choice for semi-conductor chip makers and other research applications requiring precise imaging.
