摘要:
An example semiconductor wafer includes a semiconductor layer, a dielectric layer disposed on the semiconductor layer, and a layer of the metal disposed on the dielectric layer. An example method of determining an effective work function of a metal on the semiconductor wafer includes determining a surface barrier voltage of the semiconductor wafer, and determining a metal effective work function of the semiconductor wafer based, at least in part, on the surface barrier voltage.
摘要:
Methods of fabricating a metal hard mask and a metal hard mask fabricated by such methods are described. The method includes flowing at least one metal reactant gas into a reaction chamber configured to perform chemical vapor deposition (CVD), wherein the at least one metal reactant gas includes a metal-halogen gas or a metal-organic gas. The method further includes depositing a hard mask metal layer by CVD using the at least one metal reactant gas.
