摘要
The radiation damage created by Si** plus implantation into Fe-doped semi-insulating InP at room temperature has been annealed out after capless annealing at 650 degree C for 15 min, but sufficient electrical activation of implanted Si requires higher annealing temperature. The surface quality of InP samples annealed at 750 degree C for 30 min still shows well. The maximum sheet carrier concentrations for InP wafers implanted at 150 keV with 1 multiplied by 10**1**3, 5 multiplied by 10**1**3 and 1 multiplied by 10**1**4cm** minus **2 and capless annealed at 750 degree C for 15 min are 8 multiplied by 10**1**2, 3. 9 multiplied by 10**1**3 and 6. 3 multiplied by 10**1**3cm** minus **2 respectively. The n-type InP Hall mobility implanted with 1 multiplied by 10**1**3cm** minus **2 of Si** plus at 150 keV is 2100 cm**2/V. sec.
