发明名称 SEMICONDUCTOR DEVICE WITH LOW-K SPACER
摘要 A semiconductor device includes gates and a low-k spacer. The low-k spacer includes low-k spacer portions formed upon the gate sidewalls and a low-k spacer portion formed upon a top surface of an underlying substrate adjacent to the gates. When a structure has previously undergone a gate processing fabrication stage, the gates and at least a portion of the top surface of the substrate may be exposed thereby allowing the formation of the low-k spacer. This exposure may include removing any original gate spacers, removing an original liner formed upon the original spacers, and removing any original fill material formed upon the liner.
