Used TEL / TOKYO ELECTRON Mark 7 #293819130 for sale

TEL / TOKYO ELECTRON Mark 7 is a photoresist equipment designed to resolve fine line widths, narrow spaces, and high resolution patterns on electronic circuits. The system is comprised of a powerful beam-forming unit, beam deflection and measuring systems, laser optics and optical components, scanning mirrors, and motion control systems for precise positioning. In addition, advanced automation and process control systems ensure precise operation and reliable production to meet the demands of next-generation semiconductor devices. The beam development machine within TEL MARK7 features a series of high-power laser diodes to generate an adjusted and carefully shaped output for patterning. The beam can be finely focused and attenuated with amplitude, using an adjustable DC-injected vertical scale laser diode array and adjustable laser diode bias current. The output can then be further tuned with a trinocular tool of cylindrical lenses, which are controlled by a step-type and high performance position controller. These components can precisely form a focused two-dimentional beam, with a narrow line width and highly accurate beam placement. The laser optics within the asset are designed to optimize the beam generation and deflection. The optical path layout is optimized for homogeneous illumination, low distortion, and wide range of scan field. High performance mirrors are used to increase beam deflection speeds, allowing them to move rapidly to the desired positions. Furthermore, a high-precision angled mirror allows a wide range of beam directions while retaining accuracy. The scanning and motion control systems of TOKYO ELECTRON MARK-7 provide a precise, low-noise scanning of the beam to produce the required patterns. A series of high-performance servo motors are synchronized for accurate motion and their motion controllers are capable of providing high-speed sampling and fine resolution control. This model is able to accurately position the beam at the desired focus, speed, and strength on the photoresist. Finally, the process control systems within TEL / TOKYO ELECTRON MARK-7 are designed to enable a high degree of production reliability to meet the demands of the next-generation of semiconductor devices. The software-controlled photoresist and process processes enable maintenance-free operation. It is equipped with a feedback equipment to prevent photoresist contamination and also features a feedback circuit to ensure photo stop accuracy. TEL / TOKYO ELECTRON MARK7 photoresist system is a powerful unit capable of providing high-resolution images with narrow line widths, narrow spaces, and uniform illumination. Its powerful beam-forming machine, beam deflection and measuring systems, laser optics, scanning mirrors and motion controllers, and advanced automation and control systems ensure precise operation and reliable production.
