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.

p-Xylene - Production. 1  The production of p-xylene is industrially significant, with annual demand estimated at 37 million tons in 2014, and still on the increase. [7] [8] p-Xylene is produced by catalytic reforming of petroleum naphtha as part of the BTX aromatics (benzene, toluene and the xylene isomers) extracted from the catalytic reformate.
