Used VARIAN 3290 STQ #9257988 for sale

VARIAN 3290 STQ is an advanced sputtering equipment used to deposit ultra-thin films of various materials onto a wide variety of substrates. The system uses a direct current (DC) sputtering process to provide precise control over the deposition rate, thickness, and composition of the film. The sputtering process within VARIAN 3290STQ begins when a high-frequency, low-pressure gas is introduced into the chamber, usually with the use of a dedicated turbo-molecular pump. Next, a DC voltage is applied to the substrate and the sputter sources, resulting in an electric field between them that produces ions in the gas. The energetic ions are then accelerated towards the sputter target, causing material to be sputtered off the surface. The sputtered atoms are then deposited onto the substrate, forming a thin film. 3290 STQ offers complete control over the sputtering process. The unit's voltage, power, and gas flows can be adjusted in real-time to ensure an optimal deposition. For instance, a higher voltage often increases the film deposition rate, while lower voltage can be used to create more uniform films. The machine also offers the ability to deposit multiple targets, both simultaneously and sequentially, to create complex multilayered films with tailored properties. 3290STQ is also designed to be completely automated. Its closed-loop control systems, along with its servo-controlled magnets and sources, help ensure uniform film deposition over the entire substrate. Additionally, the tool's advanced data acquisition systems enable precise characterization of the film deposition rate and composition, and can store data for archiving. Overall, VARIAN 3290 STQ is a reliable, cost-effective sputtering asset that offers advanced possibilities for the deposition of ultra-thin films. Its versatile design, with automated process control and precision monitoring, ensure a high-quality, consistent film deposition each time.
