A method for treating a semiconductor surface to form a metal-containing
layer includes providing a semiconductor substrate having an exposed
surface. The exposed surface of the semiconductor substrate is treated by
forming one or more metals overlying the semiconductor substrate but not
completely covering the exposed surface of the semiconductor substrate.
The one or more metals enhance nucleation for subsequent material growth.
A metal-containing layer is formed on the exposed surface of the
semiconductor substrate that has been treated. The treatment of the
exposed surface of the semiconductor substrate assists the
metal-containing layer to coalesce. In one embodiment, treatment of the
exposed surface to enhance nucleation may be performed by spin-coating,
atomic layer deposition (ALD), physical layer deposition (PVD),
electroplating, or electroless plating. The one or more metals used to
treat the exposed surface may include any rare earth or transition metal,
such as, for example, hafnium, lanthanum, etc.
