N Type Silicon Semiconductor (4 inch, Sb Doping)

N Type Silicon Semiconductor

N type silicon semiconductor are materials that have been doped with elements that provide extra electrons, enhancing their conductivity. Antimony (Sb) is one such doping agent used in the production of N-type silicon. The use of 4-inch wafers is common in various semiconductor applications, as this size allows for efficient production and integration into electronic devices.
