Used KOMATSU G20K2-1 #9095919 for sale

KOMATSU G20K2-1 is a wafer stepper used for semiconductor processing. It is a state-of-the-art equipment designed for high-precision and high-performance wafer stepper operations. The system is composed of four key components: the Machine Unit, the Optical Machine, the Step Adjustment Tool, and the Control Asset. The Machine Model consists of an XY stage, a three-phase direct drive motor, a beam and a vacuum chuck. The XY stage is a large platform in which the wafers are placed and on which the beam can move to accurately position and expose the wafers to the stepper's illumination equipment. The three-phase direct drive motor enables precise control over the speed of the beam, helping to reduce defects due to vibration or speed fluctuations. The beam and the vacuum chuck secure the wafer during the exposure process. The Optical System of KOMATSU G 20 K 2-1 is composed of two independent cameras that can move in the x and y directions to capture high-resolution images of the wafer. It is designed to accurately capture images of the smallest features on the wafer and to provide the stepper with the precise coordinates of each feature, allowing the tool to print the desired pattern with high accuracy. Additionally, the unit features an illumination machine composed of three different light sources that are adjustable in order to ensure optimal imaging conditions for the exposed wafer. The Step Adjustment Tool of G20K2-1 enables the tool to quickly make fine adjustments to the stepper's position and focusing to ensure that the desired pattern is accurately printed on the wafer. This asset ensures that the printed pattern is accurately aligned to the feature coordinates to produce the desired effect. Finally, the Control Model of G 20 K 2-1 is composed of a CPU and a monitor. The CPU manages the stepper's various components and functions, while the monitor can be used to display the imaging process in real time. The equipment also features a user-friendly interface that makes it easier for users to control the stepper's parameters and settings. In conclusion, KOMATSU G20K2-1 is a state-of-the-art wafer stepper designed for high-precision and high-performance operations. It is composed of four key components that enable the tool to accurately and quickly produce defined patterns on wafers.
