Abstract: A method for fabricating semiconductor device includes the steps of first forming a metal gate on a substrate and a spacer around the metal gate, in which the metal gate comprises a high-k dielectric layer, a work function metal layer, and a low-resistance metal layer. Next, part of the high-k dielectric layer is removed to form an air gap between the work function metal layer and the spacer.

Abstract: A manufacturing method of a semiconductor device includes the following steps. A barrier layer is formed in a first region and a second region of a semiconductor substrate. The barrier layer formed in the first region is thinned before a step of forming a first work function layer on the barrier layer. The first work function layer formed on the first region is then removed. The process of thinning the barrier layer in the first region and the process of removing the first work function layer in the first region are performed separately for ensuring the coverage of the first work function layer in the second region. The electrical performance of the semiconductor device and the uniformity of the electrical performance of the semiconductor device may be improved accordingly.

Abstract: A method of forming a semiconductor device is disclosed. Provided is a substrate having at least one MOS device, at least one metal interconnection and at least one MOS device formed on a first surface thereof. A first anisotropic etching process is performed to remove a portion of the substrate from a second surface of the substrate and thereby form a plurality of vias in the substrate, wherein the second surface is opposite to the first surface. A second anisotropic etching process is performed to remove another portion of the substrate from the second surface of the substrate and thereby form a cavity in the substrate, wherein the remaining vias are located below the cavity. An isotropic etching process is performed to the cavity and the remaining vias.
