Used NEMST 2002S #293610013 for sale

NEMST 2002S is an ultraviolet (UV) etcher / asher which is widely used in a multitude of scientific and industrial fields. This state of the art photolithography instrument is designed for precision etching of complex patterns in a wide range of substrate materials. 2002S offers four wafer capacity and motion axes for three dimensional etching and is capable of providing excellent patterning with extremely tight controls on etch depth, precision, and repeatability. NEMST 2002S is composed of a variety of components, such as a UV lamp, quartz top-plate, image forming optics, beam splitter and beam transporter. The UV lamp supplies the necessary exposure light, while the quartz top plate reduces the chance of exposure-generated debris during etching. The image forming optics and beam splitter are used to direct light to the wafer mount, while the beam transporter ensures an accurate exposure area. 2002S operates through a process of pre-treatment, etching, and post-treatment. During the pre-treatment stage, the quartz top-plate is cleaned, and the wafers are coated with a photoresist prior to etching. The etch is then done via the UV laser exposure of the wafer, which is controlled by the beam splitter and beam transporter to ensure consistent etch depth. Finally, the post-treatment procedure involves a process of developing the resist, chemical stripping, and resist stripping. The completed resist pattern is then ready for further processing. NEMST 2002S is very controlled and precise, with the ability to etch complex patterns with a very high degree of accuracy and repeatability. This instrument has been utilized in a wide range of industrial and scientific applications, such as mask production, OLED manufacturing, thin-film transistors, medical device, and solar cell fabrication, just to name a few. Due to its several technical advantages, such as enhanced precision, high repeatability, laser exposure accuracy, and a wide array of application uses, 2002S is considered a very important device in many industries and laboratories.
