摘要: A method for fabricating a semiconductor device is disclosed. A strained material is formed in a cavity of a substrate and adjacent to an isolation structure in the substrate. The strained material has a corner above the surface of the substrate. The disclosed method provides an improved method for forming the strained material adjacent to the isolation structure with an increased portion in the cavity of a substrate to enhance carrier mobility and upgrade the device performance. In an embodiment, the improved formation method is achieved using an etching process to redistribute the strained material by removing at least a portion of the corner to be located in the cavity.

摘要: The present disclosure provides a method for fabricating a semiconductor device that includes providing a silicon substrate, forming a gate stack over the silicon substrate, performing a biased dry etching process to the substrate to remove a portion of the silicon substrate, thereby forming a recess region in the silicon substrate, performing a non-biased etching process to the recess region in the silicon substrate, thereby forming a bottle-neck shaped recess region in the silicon substrate, and epi-growing a semiconductor material in the bottle-neck shaped recess region in the silicon substrate. An embodiment may include a biased dry etching process including adding HeO2 gas and HBr gas. An embodiment may include performing a first biased dry etching process including N2 gas and performing a second biased dry etching process not including N2 gas. An embodiment may include performing an oxidation process to the recess region in the silicon substrate by adding oxygen gas to form silicon oxide on a portion of the recess region in the silicon substrate. As such, these processes form polymer protection to help form the bottle-neck shaped recess.
