Inside Working of an Ion Implantation Machine (Semiconductor Fabrication – Correct Technical Description) An ion implantation system introduces controlled dopant atoms (such as boron, phosphorus, or arsenic) into a silicon wafer by accelerating ions at high energy and embedding them into the crystal lattice. The tool operates under high vacuum and is divided into six main internal subsystems, arranged linearly. 1. Ion Source Chamber Function: Generate charged dopant ions Dopant gas (BF₃, PH₃, AsH₃) or solid source is introduced RF or arc discharge ionizes the gas Produces positive ions (B⁺, P⁺, As⁺) Operates at low pressure (~10⁻⁴ Torr) 3D elements to model: Plasma chamber RF coils or arc electrodes Gas inlet lines Extraction aperture 2. Extraction & Acceleration Column Function: Pull ions out and accelerate them Electrostatic extraction electrodes pull ions from plasma High voltage (10 keV – 3 MeV depending on tool) Defines ion energy → determines implant depth Key concept: Energy = pene
