1.08 Extrinsic semiconductor. To produce extrinsic semiconductor material specific amounts of impurity are added to the pure intrinsic semiconductor. This process is called doping and the impurity atoms are called donor atoms.There are two types of extrinsic semiconductor which are manufactured, P type semiconductor and N type semiconductor.his process is called doping and the impurity atoms are called donor atoms.

The remainder of primary production comes from ores in which copper is present as silicates, sulfates, carbonates and oxides, which have been formed by the weathering and oxidation of sulfide minerals. About 30% of all copper production is recovered from secondary and scrap materials which are recycled.
