摘要:
A buffer layer and a high-k metal oxide dielectric may be formed over a smooth silicon substrate. The substrate smoothness may reduce column growth of the high-k metal oxide gate dielectric. The surface of the substrate may be saturated with hydroxyl terminations prior to deposition.

A method for making a semiconductor device is described. That method comprises forming an oxide layer on a substrate, and forming a high-k dielectric layer on the oxide layer. The oxide layer and the high-k dielectric layer are then annealed at a sufficient temperature for a sufficient time to generate a gate dielectric with a graded dielectric constant.

Methods of forming a microelectronic structure are described. Those methods may include forming a gate dielectric layer on a substrate, forming a metal gate layer on the gate dielectric layer, and then forming a polysilicon layer on the metal gate layer in situ, wherein the metal gate layer is not exposed to air.
