    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: This description relates to a method including forming an interlayer dielectric (ILD) layer and a dummy gate structure over a substrate and forming a cavity in a top portion of the ILD layer. The method further includes forming a protective layer to fill the cavity. The method further includes planarizing the protective layer. A top surface of the planarized protective layer is level with a top surface of the dummy gate structure.

    摘要: Preventing a chemical vapor deposition (CVD) chamber from particle contamination in which a higher low-frequency radio frequency (LFRF) power and longer process time are provided to vacate the chamber and perform a pre-heat process. Following that, a pre-oxide layer is formed on the chamber wall, while a high-frequency radio frequency bias is provided to the chamber. The high-power LFRF is continuously provided to the chamber to sustain the temperature of the chamber, and then a main oxide layer deposition process is performed. The method is able to form an oxide layer of better quality on a CVD chamber wall, so as to solve the particle problem in the prior art. Therefore, yield is improved and the maintenance cost is reduced.
