Deep levels in n-type and p-type Si
due to Co-sputtering and RTA (Rapid Thermal Annealing) at various temperatures is investigated by using DLTS (Deep Level Transient Spectroscopy) technique. It is found that Co-related defect levels at (Ec-0 20eV)
(Ec-0.36eV)
(Ec-0.40eV) and(Ec-0.45eV) are produced only for n-type material. The concentration of these defects is rather small and ranges between 2×1010 and 1×1011cm-3. These defect levels can be attributed to substitutional Co atoms
interaction of Co with RTA and Co-defect complexes.
