    摘要: A new method of forming a dual damascene structure involves forming a via-level precursor structure on a substrate and spin coating an oxide protective layer over the bottom anti-reflective coating, which is the last layer of the via-level precursor structure. A trench-level photoresist layer is deposited over the oxide protective layer to form a trench pattern etch mask. The oxide protective layer protects the BARC layer and the via plugs from photoresist removing process. When and if the trench-level photoresist layer is to be reworked, the trench-level photoresist layer is simply removed without removing the BARC layer and the via plugs under the oxide protective layer.

    摘要: An integrated circuit device is disclosed. The disclosed device provides improved control over a surface proximity and tip depth of integrated circuit devices. An exemplary integrated circuit device disclosed herein 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: 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.
