Profile: Testbourne Ltd supplies metals, alloys & compounds to industries such as semiconductors, thin-films, electronics and electro-optics. We also offer scientific instruments. The thin film deposition controllers provide automatic rate control of single or multi-layer film depositions. They have the ability to control many of the vacuum systems peripherals such as multi-pocket indexers, source shutters, gas valves, etc. They are typically used in production systems. Thin film deposition monitor simply measure the deposition rate and thickness but do not provide rate control. They are typically used in development systems with manual control. They are also used in sputtering where rate control is not required.
