Atomic Layer Deposition of Transition Metal Thin Films

Wayne State University researchers have circumvented precursor reactivity problems by developing a three-step deposition scheme that entails a transition metal precursor, an organic acid, and a reducing agent. This novel process can produce high purity, low resistivity copper films at 100 °C, which is a significant breakthrough in transition metal ALD...
