Used NIKON NSR S204 #9225054 for sale

NIKON NSR S204 Wafer Stepper is a one-of-a-kind machine that has revolutionized the accuracy and capability of silicon wafer dicing operations. The machine is a high-resolution, high-speed imaging system that combines precision optics, precision motor packages, and a finely tuned suite of software tools. As such, it is capable of producing extremely fine feature sizes (down to 50 microns) with remarkable accuracy. NSR S204 Wafer Stepper utilizes a unique optical element known as a scanning stage. This stage is responsible for positioning and orienting each silicon wafer accurately across the full viewing field. It then raster scans each wafer in the X,Y and Z axes to create the desired pattern of etching or drilling. A sophisticated image processing system digitizes and coordinates the image data for proper registration of data points and feature sizes. A light source is also used to provide the necessary backlighting for precision imaging. To ensure accuracy, NIKON NSR S204 utilizes two distinct types of wafer handling systems, a fixed stage and a movable stage. The fixed stage, which is attached to the scanning stage, is designed to maintain accuracy by keeping the wafer stationary as the scanning of the images proceeds. The movable stage, meanwhile, is attached to a motorized actuator which allows the wafer to be moved and positioned throughout the imaging process. This ensures that feature size and patterns of points remain consistent throughout the process. The imaging and dicing operations of NSR S204 Wafer Stepper are powered by a robust software package which includes features such as: pattern rotation and alignment correction, nonlinear image compensation, and image overlay capabilities. This allows the system to adjust parameters and tolerances as needed to keep operation speed and accuracy at peak levels. In addition, the machine also offers advanced tools such as 3D laser cutting, which can be used to create intricate patterns or channels. NIKON NSR S204 Wafer Stepper is the ideal machine for advanced production and prototyping for silicon wafer applications. Its excellent accuracy and speed make it the machine of choice for precision wafer dicing and related applications. With its easy-to-use software, advanced image processing, and various wafer handling options, NSR S204 Wafer Stepper is a powerful and reliable solution for the dicing needs of the modern semiconductor industry.
