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 an integrated circuit device. In an embodiment, the method achieves improved control by forming a doped region and a lightly doped source and drain (LDD) region in a source and drain region of the device. The doped region is implanted with a dopant type opposite to the LDD region.
