TEL / TOKYO ELECTRON Mark 8 is a state-of-the-art photoresist equipment designed for the production of semiconductors. The system is capable of generating very high-resolution patterns on the wafer allowing for the fabrication of very fine electronic structures. The unit uses an electron beam to expose a sensitive film coating on the wafers to a light beam. This film is comprised of a photoresist that is most commonly composed of polymethylmethacrylate, amorphous silicon dioxide, and other active isolation materials. The electron beam interacts with the resist, causing it to change its properties. As a result, a pattern is formed onto the resist layer on the wafer which can be used to construct electronic devices such as transistors. The exposure process begins with a vacuum chamber in which a beam of electrons is produced. The beam passes through a machine of columns, enabling the beam to be focused and controlled over the wafer's thickness. This is done by controlling the vacuum pressure, electron energy level, and the arc voltage which helps to steer the beam. The exposure process is regulated by an electronic control unit, which both monitors and regulates the progress of the exposure. This tool enables the user to enter in variables such as exposure energy levels, blocking heights, and wafer temperatures so that each exposure has the optimal conditions for the specific requirements of the circuit being created. The asset is equipped with a wafer handling unit, which automates the loading and unloading of the substrates into the model. This eliminates the need for manual handling, reducing the possibility of damage, contamination, and mis-alignments. The entire equipment is automated, meaning that the user need not be present during the exposure process unless otherwise desired. Finally, the system is capable of profiling, storing, and summarizing exposure results. This enables users to verify conformity to predetermined specifications, resulting in a higher degree of accuracy for the circuit profiles. Overall, TEL MARK8 is an advanced photoresist unit that provides users with a reliable and powerful means of creating high-quality and accurate circuit patterns for a variety of applications.
