SUMMARY

The discussion centers on the fabrication of a PIN diode using boron (P-type), silicon (N-type), and phosphorus (N-type) as doping materials. The user successfully created the diode by etching contacts on a silicon wafer and doping with boron and phosphorus, resulting in a defined I-region. They measured the I-V characteristics but lack a reference formula for comparison, seeking assistance to validate their measurements.

PREREQUISITES
  • Understanding of semiconductor physics, particularly P-N junctions.
  • Familiarity with doping processes in semiconductor fabrication.
  • Knowledge of I-V characteristic measurement techniques.
  • Experience with silicon wafer processing and etching methods.
NEXT STEPS
  • Research the Shockley diode equation for I-V characteristics of diodes.
  • Study the effects of doping concentrations on the performance of PIN diodes.
  • Learn about semiconductor device characterization techniques.
  • Explore advanced topics in semiconductor physics, such as minority carrier dynamics.
USEFUL FOR

Electrical engineers, semiconductor researchers, and students involved in device fabrication and characterization will benefit from this discussion.

Hii...

I already fabricated PIN diode using boron (P), Si (N-type), and phosphorus (N). For the method, I etching two contact at Si wafer then doping the boron and phosphorus... there are width I-region (Si) between the contact.

A already measured the I-V characteristic of PIN diode but don't have any formula or reference for compare with the measurement. I want know the formula to prove my IV Characteristic PIN diode. help me...??


Picture my fabricated PIN diode :
