Zusammenfassung:Methods of lightly implanting platinum, iridium, osmium, erbium, ytterbium, dysprosium, and gadolinium in semiconductor material in shallow depths by plasma-immersion ion implantation (PIII) and/or pulsed PIII are provided herein. Methods include depositing a liner layer prior to masking and implanting features to form n-type and p-type semiconductors and implanting materials through the liner layer. Methods are suitable for integration schemes involving fabrication of fin-type field effect transistors (FinFETs).
