Used NIKON EX12 #293776343 for sale

NIKON EX12 is a state-of-the-art wafer stepper designed for the advanced photolithography process used in semiconductor fabrication. It has a full 1:1 projection optics equipment that enables high-level precision imaging on the wafer, producing accurately dimensioned patterns with sharp details. This makes it ideal for semiconductor applications, including device fabrication and sub-micron feature alignment. NIKON EX 12 uses a two-stage reduction system to minimize distortions and aberrations, resulting in an improved final image. It incorporates the latest computer numerical control (CNC) technology to ensure smooth, accurate, and repeatable operations. The wafer stepper can generate patterns ranging from 80nm to 20µm pitch with an 800mm Field Lens Projection (FLP) unit. EX12 also features high stability during prolonged operation. Its advanced closed-loop servo drive machine helps reduce the total stepper vibration, thermally induced distortions, and air turbulences. Resulting in precise and consistent wafer alignment and imaging. The stepper is equipped with an advanced pattern recognition tool, which enables complex pattern imaging with a high degree of accuracy. It also features different scanning modes, such as linear, variable, and spiral scanning. The variable scan mode is especially helpful for wafers with longer exposure times since it can help optimize imaging exposure. The stepper is also equipped with an integrated measurement asset, which minimizes operator intervention and improves process control. It can generate reticle coordinates in real time, allowing operators to accurately check product shapes on the fly. EX 12 also has the capacity to support up to two stages of alignment and to transfer a semiconductor wafer between stages. This helps make the chip production process more efficient. The wafer stepper supports multiple types of software used in the semiconductor fabrication process including the full range of EDA solutions. Overall, NIKON EX12 is an advanced wafer stepper designed to meet the most demanding processes in the semiconductor industry. It features excellent imaging precision, high levels of process control and automation, and a range of features designed to make the semiconductor fabrication process easier.
