|Abstract:||Electrically active defects induced by the formation of nickel-platinum alloy monosilicide (formed at 600-800°C) has been studied in n-type silicon using deep level transient spectroscopy and transmission electron microscopy measurements. A Ni-related electron trap level at Ec-0.42 eV is observed after silicidation at 600°C or above and a Pt-related electron trap level at Ec-0.50 eV is detected after silicidation at 700°C or above. Two hole trap levels at Ev+0.22 and Ev+0.28 eV are also detected, Ev+0.22 eV level for silicidation at 700°C or above and Ev+0.28 eV level for 600 °C silicidation. For the sample silicided at 600°C, an additional electron trap level (located at Ec -0.16 eV) with a broad spectral peak is detected in the near-surface region (|
