Used SEMITOOL 840 #9185721 for sale

SEMITOOL 840 is a photoresist equipment designed for the deposition of thin, uniform layers of photoresist over the surfaces of substrates. Photoresist, also known as photosensitive polymers, provide the necessary thin-film barrier layers between the substrate and the semiconductor wafers or other components to be deposited, thus ensuring the optimum electrical performance and reliable manufacturing of electronic components. 840 photoresist system utilizes a high-precision, specific-volume dispense unit and precision-controlled spray valves that provide a uniform film deposition. The machine is capable of depositing a thin layer of photoresist substantially equal to the thickness of a monolayer of polysiloxane photoresist, allowing for accurate and continuous layer thickness control. SEMITOOL 840 tool is highly compact and stable, with a low vibration-absorption capability and low maintenance requirements. The asset is also equipped with a low-displacement dispense model which allows for precise metrification of the thickness of the photoresist layer being deposited. Finally, the unique wafer transport mechanism ensuring that the photoresist is deposited directly onto the surface of the wafer in a uniform manner. 840 is highly reliable and cost-effective equipment for delivering superior thin-film polymer deposition and excellent electrical performance for manufacture of electronic components. It utilizes advanced technologies to minimize downtime, efficiently reduce drift, and ensure reliable deposition of thin, uniform layers of photoresist. This system is highly suited for large-scale and long-term production environments with high throughput requirements. SEMITOOL 840 offers an ideal solution for efficient, cost-conscious, and reliable photoresist deposition.
