Used AMAT / APPLIED MATERIALS DPS #293747939 for sale

AMAT / APPLIED MATERIALS DPS (Dry Plasma Strip) is a piece of equipment used for etching and ashing. This machine uses a combination of plasma and dry oxygen to polish and pattern surfaces of substrates like wafers, masks, or masks on wafers. It is a specialized etcher for removing thin layers of organic, inorganic, and polymeric materials from the surface of a wafer. The dry plasma stripping process begins with an active or positive gas as a source of energy, typically oxygen. The gas is then symmetrically pulsed to a very high frequency, creating a plasma. The plasma is then injected into a vacuum chamber where the wafer and substrate surfaces are exposed to the plasma for a certain amount of time. This causes the deposited molecules or surface organics to be stripped from the surface. The particles that are left behind are then carried away in the exhaust system of the machine. The etching and ashing are both done in a single process in AMAT DPS. The ashing process is typically done after the etching process has been completed, as it removes the residue and debris that is left behind after etching. This process leaves the top layer of the substrate surface clean and smooth, and it also improves the adhesion, surface morphology, and electrical properties of the substrate. Additionally, APPLIED MATERIALS DPS etcher/asher has been designed to operate at a high degree of efficiency. The etching and ashing processes can be completed quickly, and the results are consistent and repeatable. By providing a uniform and consistent etching and ashing process, DPS ensures the highest level of quality control for all wafer and substrate surfaces. In short, AMAT / APPLIED MATERIALS DPS Dry Plasma Strip is an ideal etching and ashing machine for etching and ashing of wafer and substrate surfaces. It uses a combination of plasma and dry oxygen to strip thin layers of organic, inorganic, and polymeric materials from the surface. Additionally, the fast process and uniform results ensure a high level of quality control and uniformity.
