    摘要: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved control over a surface proximity and tip depth of integrated circuit devices. An exemplary integrated circuit device achieved by the method has a surface proximity of about 1 nm to about 3 nm and a tip depth of about 5 nm to about 10 nm. The integrated circuit device having such surface proximity and tip depth includes an epi source feature and an epi drain feature defined by a first facet and a second facet of a substrate in a first direction, such as a {111} crystallographic plane of the substrate, and a third facet of the substrate in a second direction, such as a { 100} crystallographic plane of the substrate.

    摘要: A method for cleaning a diffusion barrier over a gate dielectric of a metal-gate transistor over a substrate is provided. The method includes cleaning the diffusion barrier with a first solution including at least one surfactant. The amount of the surfactant of the first solution is about a critical micelle concentration (CMC) or more. The diffusion barrier is cleaned with a second solution. The second solution has a physical force to remove particles over the diffusion barrier. The second solution is substantially free from interacting with the diffusion barrier.

    摘要: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved control over a surface proximity and tip depth of integrated circuit device. In an embodiment, the method achieves improved control by forming a lightly doped source and drain (LDD) region that acts as an etch stop. The LDD region may act as an etch stop during an etching process implemented to form a recess in the substrate that defines a source and drain region of the device.
