    摘要: An opening in a dielectric layer having a unique barrier layer structure is provided. In an embodiment, the opening is a via and a trench. The barrier layer, which may comprise one or more barrier layers, is formed such that the ratio of the thickness of the barrier layers along a sidewall approximately midway between the bottom of the trench and the top of the dielectric layer to the thickness of the barrier layers along the bottom of the trench is greater than about 0.55. In another embodiment, the ratio of the thickness of the barrier layers along a sidewall approximately midway between the bottom of the trench and the top of the dielectric layer to the thickness of the barrier layers along the bottom of the via is greater than about 1.0. An underlying conductive layer may be recessed.

    摘要: A composite barrier layer provides superior barrier qualities and superior adhesion properties to both dielectric materials and conductive materials as the composite barrier layer extends throughout the semiconductor device. The composite barrier layer may be formed in regions where it is disposed between two conductive layers and in regions where it is disposed between a conductive layer and a dielectric material. The composite barrier layer may consist of various pluralities of layers and the arrangement of layers that form the composite barrier layer may differ as the barrier layer extends throughout different sections of the device. Amorphous layers of the composite barrier layer are generally disposed to form boundaries with dielectric materials and crystalline layers are generally disposed to form boundaries with conductive materials such as interconnect materials.

    摘要: A loadlock. The loadlock for wafers includes a chamber, a pedestal, a retractable shaft, and a bellows. The chamber has a plurality of walls and a bottom surface. The pedestal supports a cassette and is disposed in the chamber. The retractable shaft has a top end and a bottom end. The top end is connected to the pedestal and the bottom end is connected to the bottom surface as a reference for positioning the pedestal. The bellows has a first end and a second end. The first end is disposed on the pedestal and the second end is sealed at the bottom end of the retractable shaft. Preferably, the retractable shaft is fully enclosed by the bellows.
