A method of doping a compound semiconductor substrate includes: setting a first substrate temperature for the compound semiconductor substrate in a first temperature range; implanting a dopant species into the compound semiconductor substrate at a first ion dose at the first substrate temperature; and annealing the compound semiconductor substrate after the implanting the ions. In conjunction with the annealing, the first ion dose is effective to generate a first dopant activation in the first temperature range higher than a second dopant activation resulting from implantation of the first ion dose at a second substrate temperature below the first temperature range, and is higher than a third dopant activation resulting from implantation of the first ion dose at a third substrate temperature above the first temperature range.
