    摘要: A method of forming a Non-planar FET is provided. A substrate is provided. An active region and a peripheral region are defined on the substrate. A plurality of VSTI is formed in the active region of the substrate. A part of each VSTI is removed to expose a part of sidewall of the substrate. Then, a conductor layer is formed on the substrate which is then patterned to form a planar FET gate in the peripheral region and a Non-planar FET gate in the active region simultaneously. Last, a source/drain region is formed on two sides of the Non-planar FET gate.

    摘要: A method of forming a semiconductor device is provided. A first interfacial material layer is formed by a deposition process on a substrate. A dummy gate material layer is formed on the first interfacial material layer. The dummy gate material layer and the first interfacial material layer are patterned to form a stacked structure. An interlayer dielectric (ILD) layer is formed to cover the stacked structure. A portion of the ILD layer is removed to expose a top of the stacked structure. The stacked structure is removed to form a trench in the ILD layer. A second interfacial layer and a first high-k layer are conformally formed at least on a surface of the trench. A composite metal layer is formed to at least fill up the trench.
