Doping
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Doping is the deliberate introduction of impurities into an intrinsic semiconductor to modify its electrical conductivity. It is a fundamental process for creating p-type and n-type regions in semiconductor devices.
Example in context
“The fabrication engineer carefully controlled the doping concentration to achieve the desired threshold voltage for the MOSFET.”
“İmalat mühendisi, MOSFET için istenen eşik voltajına ulaşmak için katkılama konsantrasyonunu dikkatlice kontrol etti.”
Where engineers use it
Doping is used in semiconductor fabrication to create n-type and p-type regions. An engineer must control doping levels when designing diodes, transistors, and integrated circuits. It directly affects carrier concentration and device performance.
Synonyms: impurity addition, dopant incorporation
Antonyms: intrinsic, undoped
Practice: can you use “Doping” at work?
A junior engineer is troubleshooting a diode with unusually high leakage current. Examine the doping profiles and explain how incorrect doping can cause this issue.
