Zusammenfassung:A patterned anti-reflective coating may be used as a selective implant-blocking layer during fabrication of an integrated circuit transistor. In particular, the anti-reflective coating may be used as a gate sidewall spacer to block at least some dopants from an integrated circuit substrate beneath the gate sidewall spacer. Moreover, a single mask may be used when fabricating source and drain extension regions and source and drain regions of an integrated circuit transistor.
