Cobalt Foil For Semiconductors

Semiconductor grade cobalt foil must possess a series of special properties to meet advanced process requirements. Firstly, the ultra-high purity of over 99.995% ensures that no pollution sources are introduced during the chip manufacturing process. Next is the nanoscale surface flatness, and the surface roughness needs to be controlled within 0.1 μ m to meet the ultimate requirements of extreme ultraviolet lithography technology for substrates.
In terms of thermal performance, cobalt foil needs to have excellent thermal stability, be able to withstand high-temperature process environments such as chemical vapor deposition, and its thermal expansion coefficient must be perfectly matched with the silicon substrate. In terms of electrical performance, it is required to have extremely low resistivity and excellent resistance to electromigration, which is crucial for reducing interconnect delay and improving chip reliability.
