    摘要: A method of forming an integrated circuit structure includes providing a semiconductor substrate including a top surface; forming an opening extending from the top surface into the semiconductor substrate; and performing a first deposition step to fill a first dielectric material into the opening. The first dielectric material is then recessed. A second deposition step is performed to fill a remaining portion of the opening with a second dielectric material. The second dielectric material is denser than the first dielectric material. The second dielectric material is recessed until a top surface of the second dielectric material is lower than the top surface of the semiconductor substrate.

    摘要: A method of forming a metal-oxide-semiconductor (MOS) transistor device is disclosed. A semiconductor substrate is prepared first, and the semiconductor substrate has agate structure, a source region and a drain region. Subsequently, a stress buffer layer is formed on the semiconductor substrate, and covers the gate structure, the source region and the drain region. Thereafter, a stressed cap layer is formed on the stress buffer layer, and a tensile stress value of the stressed cap layer is higher than a tensile stress value of the stress buffer layer. Since the stress buffer layer can prevent the stressed cap layer from breaking, the MOS transistor device can be covered by a stressed cap layer having an extremely high tensile stress value in the present invention.

    摘要: A semiconductor device having fins and a method of manufacture are provided. A patterned mask is formed over a substrate. Trenches are formed in the substrate and the trenches are filled with a dielectric material. Thereafter, the patterned mask is removed and one or more etch processes are performed to recess the dielectric material, wherein at least one of the etch processes is an etch process that removes or prevents fences from being formed along sidewalls of the trench. The etch process may be, for example, a plasma etch process using NH3 and NF3, an etch process using a polymer-rich gas, or an H2 etch process.

    摘要: A method of forming an integrated circuit structure includes providing a substrate; forming a first hard mask layer over the substrate; forming a second hard mask layer over the first hard mask layer; patterning the second hard mask layer to form a hard mask; and, after the step of patterning the second hard mask layer, baking the substrate, the first hard mask layer, and the hard mask. After the step of baking, a spacer layer is formed, which includes a first portion on a top of the hard mask, and a second portion and a third portion on opposite sidewalls of the hard mask. The method further includes removing the first portion of the spacer layer; removing the hard mask; and using the second portion and the third portion of the spacer layer as masks to pattern the first hard mask layer.

    摘要: A method for rounding the corners of a shallow trench isolation is provided. A preferred embodiment comprises filling the trench with a dielectric and recessing the dielectric to expose a portion of the sidewalls of the trench adjacent to the surface of the substrate.
