Abstract
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.
