    摘要: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. In an example, the method includes providing a substrate; forming a gate structure over the substrate; removing portions of the substrate to form a first recess and a second recess in the substrate, such that the gate structure interposes the first recess and the second recess; forming a nitrogen passivation layer in the substrate, such that the first recess and the second recess are defined by nitrogen passivated surfaces of the substrate; and forming doped source and drain features over the nitrogen passivated surfaces of the first recess and the second recess, the doped source and drain features filling the first and second recesses.
