Used SEMES KWET 300 #9241265 for sale

SEMES KWET 300 is a photoresist system that enables cost-effective and high-precision patterning of semiconductor and other electronic materials. It is composed of a range of components, all designed to enable the user to control the exposure level of a substrate and pattern it with fine lines and other patterns. The major components are the exposure source, a substrate holder, a series of optical filters, a light shielding plate, and a pattern generator. The exposure source is typically a high-intensity light source, such as an ultra-violet lamp, that produces short and controlled pulses of light. The light is then reflected by the optical filters and the light shielding plate before casting a pattern onto the substrate holder. The substrate holder is designed to hold and precisely locate any chosen device during the exposure process. The holder is usually composed of an optically transparent material that facilitates the passage of light, and is often etched or coated with a patterning material to provide additional control over the substrate's location. The optical filters are a critical part of the system. They are designed to reduce the intensity of the light source and minimize the spread of its light over any non-essential areas. This ensures that the pattern generated by the exposure process is more precise, and that unwanted portions of the substrate are not patterned. The light shielding plate ensures that the patterns generated by the exposure process are not affected by external sources of light. It consists of a special black material that effectively absorbs and blocks unwanted light without causing any damage to the substrate. Finally, the pattern generator is used to create a specific pattern on the substrate. It typically consists of a spinning wheel or a motorized mask that cycles through predefined patterns quickly and accurately. This is the final step in the patterning process and is used to ensure consistency in the final result. All of these components work in conjunction to create a cost-effective and precise patterning process. KWET 300 is ideal for applications such as semiconductor device fabrication, contact cutting, wafer probing, metrology, and more. It is an invaluable tool for those looking to perform high-precision patterning of a variety of different materials.
