    Abstract: A method of forming a semiconductor device is provided. A material layer, a first flowing material layer and a first mask layer are sequentially formed on a substrate. A first etching process is performed by using the first mask layer as a mask, so as to form a first opening in the material layer. The first mask layer and the first flowing material layer are removed. A filler layer is formed in the first opening. A second flowing material layer is formed on the material layer and the filler layer. A second mask layer is formed on the second flowing material layer. A second etching process is performed by using the second mask layer as a mask, so as to form a second opening in the material layer.

    Abstract: The metal gate structure includes at least a substrate, a dielectric layer, first and second trenches, first metal layer and second metal layers, and two cap layers. In particular, the dielectric layer is disposed on the substrate, and the first and second trenches are disposed in the dielectric layer. The width of the first trench is less than the width of the second trench. The first and second metal layers are respectively disposed in the first trench and the second trench, and the height of the first metal layer is less than or equal to the height of the second metal layer. The cap layers are respectively disposed in a top surface of the first metal layer and a top surface of the second metal layer.

    Abstract: A method of forming a contact hole includes providing a substrate. A nitrogen-containing dielectric layer, a first material layer, a second material layer, an oxygen-containing dielectric layer and a patterned photoresist layer cover the substrate from bottom to top. Then, the oxygen-containing dielectric layer is etched by taking the second material layer as a first etching stop layer to form a patterned oxygen-containing dielectric layer. Latter, the second material layer is etched by taking the first material layer as a second etching stop layer to form a patterned second material layer. Subsequently, the first material layer is etched by taking the nitrogen-containing dielectric layer as a third etching stop layer to form a patterned first material layer. Finally, the nitrogen-containing dielectric layer is etched until the substrate is exposed.
