P-type wafer
WebNov 17, 2024 · P-type silicon wafers have numerous positively-charged holes. To produce an N-type doped silicon wafer, elements like phosphorus, arsenic, or antimony will be added. N-type silicon wafers have a negatively-charged electron in them. The quantity of dopant discovered in the wafer will ascertain if it is degenerate or extrinsic. WebP-type, dominant charge carriers are holes. Whether a wafer is P-type or N-type will affect the electrical response of any device manufactured. 3. Crystallographic Orientation Wafers are grown as single crystals that have an ordered, regular and repeating structure.
