摘要： The present application discloses a semiconductor structure and a method for manufacturing the same. Compared with conventional approaches to form contacts, the present disclosure reduces contact resistance and avoids a short circuit between a gate and contact plugs, while simplifying manufacturing process, increasing integration density, and lowering manufacture cost. According to the manufacturing method of the present disclosure, second shallow trench isolations are formed with an upper surface higher than an upper surface of the source/drain regions. Regions defined by sidewall spacers of the gate, sidewall spacers of the second shallow trench isolations, and the upper surface of the source/drain regions are formed as contact holes. The contacts are formed by filling the contact holes with a conductive material. The method omits the steps of etching for providing the contact holes, which lowers manufacture cost. By forming the contacts self-aligned with the gate, the method avoids misalignment and improves performance of the device while reducing a footprint of the device and lowering manufacture cost of the device.

摘要： The present invention relates to a semiconductor device and a method for manufacturing the same. According to the present invention, when a gate is formed via a replacement gate process, a portion of a work function metal layer and a portion of a first metal layer are removed after the work function metal layer and the first metal layer are formed, and then the removed portions are replaced with a second metal layer. A device having such a gate structure greatly reduces the resistivity of the whole gate, due to a portion of the work function metal layer with a high resistivity being removed and the removed portion being filled with the second metal layer with a low resistivity, thereby AC performances of the device are improved.
