Used SEMITOOL WST-308 #9351546 for sale

SEMITOOL WST-308 Photoresist Equipment is a chemical process system that is used to develop patterns in electronic circuits and other electronic components. It is designed to meet the stringent requirements of the electronics industry. SEMITOOL WST 308 unit consists of a power supply, a photoresist application station, a photoresist cook tank, a development tank, and a stripping tank. The power supply provides the necessary voltage requirements for WST-308 machine. It provides the regulated output current, controlled by an electronic programmable timer. This allows the power supply to be adjusted to the correct power level for application of the photoresist material. The photoresist application station is used to apply a uniform and uniformly thin film of photoresist on the surface to be exposed. The film is produced from a liquid solution of photoresist materials. A conveyor belt transports the wafer the required distance for uniform application. The photoresist cook tank is used for baking the photoresist to harden the material before lithography is performed. This produces a fine grained uniform layer of photoresist. After baking, the wafer is moved to a development tank for exposures. The development tank is used for lithography. This tank is equipped with a powerful ultraviolet light source and a digital stepper motor to control the step size. The UV light is used to expose the photoresist layer with the required pattern. The development tank can be programmed with a series of patterns. Finally, the stripping tank is used to remove the exposed photoresist layer. The stripping tank is filled with a stripping solution and the wafer is lowered into the tank. The stripping process takes only a few seconds and the photoresist layer is removed. WST 308 Photoresist Tool is used in the electronics industry to produce complex and intricate patterns. The asset is reliable and consistently produces high quality results with little variation between cycles. The model is designed to produce 25nm to 40nm of photoresist deposition with no burrs, overhang or defects present. SEMITOOL WST-308 is a reliable tool for designing electronic components.
