Abstract
A semiconductor device includes a workpiece and a first material layer disposed over the workpiece. The first material layer has a first number of atoms at a surface. A seed layer is disposed over the first material layer. The seed layer includes a chemisorbed monolayer of a second number of atoms at the surface having a surface coverage of at least 0.5 such that the ratio of the number of first atoms at the surface to the number of second atoms at the surface is no more than 2:1. The second atoms of the seed layer include oxygen or nitrogen.
