Intevac ENERGi? utilizes a continuous flux ion implantation technique and active substrate coolingto create a distinct junction profile and implant-induced amorphous layer。 It was experimentally demonstrated thatthe “pulsed” ion implantation techniques used by beamline ion implantation and plasma immersion ion implantationsuffer from end-of-range defects。 This report also studied dopant activation by various thermal anneal schemesincluding a simulated firing furnace anneal, and showed a possibility of using the firing furnace annealing as a soleimplant annealing process as a result of the mechanism of solid phase epitaxial re-growth (SPER)。 J_(0e) data showedthat the defect free re-crystallization achieved by continuous flux implantation and active wafer cooling forms highquality emitters。
