SUMMARY
Semiconductor doping is a critical process for modifying the electrical properties of materials like silicon and gallium arsenide. N-type doping is achieved using phosphorous, while p-type doping utilizes boron. The doping process occurs beneath the surface layer of the substrate, typically under high vacuum pressures of 1E-6 torr. Techniques such as sputtering are employed on the surface, and temperature management is essential to prevent substrate damage, often involving water cooling systems during higher current implants.
