Used NIKON i12 #293603629 for sale

NIKON i12 is a high-accuracy wafer stepper used for lithography and precision patterning in the semiconductor industry. It is capable of producing sub-micron feature sizes and flat, finely patterned surfaces. NIKON I 12 is compatible with both soft and hard photomasks, so it is suitable for a variety of applications. I12 features a powerful optical equipment that is used to project a pattern onto the workpiece plate. This system comprises an alignment unit, a mask changer that holds the original mask in position, and a set of high-resolution lenses. The lenses are designed to focus light into a fine spot at the retina of the mask. They also provide on-axis alignment, so the spot is accurately aligned with the reticle grid. I 12 also boasts a range of features designed to maximize its accuracy and speed. The CircleField Correction Machine (CFCS), for example, compensates for wobble in the wafer stepper's rotary stage. There is also a specialized grid generator, known as MetraGrid, which enables users to generate patterns with extraordinary accuracy. NIKON i12 also includes an Advanced Machine Control (AMC) tool, which provides an intuitive, automated control asset. This model is capable of achieving maximum alignment accuracy, plus a range of additional functions; for example, it can automatically detect and correct for any errors in the marking pattern, as well as calculate optimal exposure time. NIKON I 12 also provides photomask alignment accuracy of up to 0.15 microns. This allows for highly reproducible patterns and exacting dimensional control. In addition, the stepper has a multi-axis motor control function that enables it to navigate the wafer, enabling accurate alignment and registration when multiple exposure steps are required. This feature also makes i12 suitable for multiple exposure and multilevel lithography. Finally, I 12 is designed to provide long-term reliability, and is equipped with a range of fault detection and preventative maintenance functions. It also comes with NIKON renowned online support services and a comprehensive suite of software applications.
