WebTable 1 gives the maximum argon ion beam currents for the graphite ion optics over a range of ion beam voltages. The recommended accelerator voltages (negative) are 15 percent of the beam voltages (see Section 4.5), except for the 100 V beam. As was shown in Figure 2a, some spreading of the beam will occur when a lower ion current is used ... WebConsequently, a single parameter approach that relies solely on the ion beam current can lead to inconsistent ion beam geometry. Furthermore, due to the different ion beam geometries, extra time must be spent on ion beam measurements, parallel setup, uniformity setup and implantation dose control for each wafer batch.
