Definition
An ion implanter ionizes a source species, selects and accelerates the desired ions, shapes and scans the beam, and controls wafer angle, temperature, charge, dose, and energy to create a repeatable implanted depth and lateral distribution.
Process position
Inputs
- Patterned or blanket wafer
- Dopant source
- Dose and energy recipe
- Wafer orientation data
Outputs
- Implanted wafer
- Dose and beam telemetry
- Tool contamination record
How it works
- 01Generate and analyze ion species
- 02Accelerate to target energy
- 03Shape and scan beam
- 04Control wafer angle and temperature
- 05Integrate dose and unload
Role in the production flow
The implanter defines an as-implanted species distribution; subsequent annealing activates dopants and repairs lattice damage. Dose, energy, angle, beam purity, charge control, and thermal history therefore need joined qualification.
An accelerator and beamline system that introduces controlled dopant or modifying species into a wafer with selected dose and energy.
Boundary: The cited manufacturers document the equipment category and its intended uses; this record does not independently validate vendor performance claims or rank products.
Qualification and production boundaries
Equipment fit depends on required species, energy and dose range, beam current, contamination segregation, wafer charging sensitivity, temperature control, angular accuracy, throughput, and the downstream activation process.
Equipment fit depends on required species, energy and dose range, beam current, contamination segregation, wafer charging sensitivity, temperature control, angular accuracy, throughput, and the downstream activation process.
Boundary: Actual acceptance limits, recipes, throughput, availability, and ownership economics are product-, process-, site-, and contract-specific.
