摘要:
A semiconductor device and a method for manufacturing the same are disclosed. The disclosed semiconductor device includes a semiconductor substrate having a device isolation structure for delimiting an active region, the active region being recessed and grooves being defined in channel forming areas of the active region; gates formed in and over the grooves; gate spacers formed on both sidewalls of the gates over portions of the recessed active region which are positioned on both sides of the gates; an LDD region formed in the active region under the gate spacers; junction areas formed in the active region on both sides of the gates including the gate spacers; and landing plugs formed on the junction areas.
