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 AMMONIA MANUFACTURING PROCESS Ammonia is produced in a process known as the Haber process, in which nitrogen and hydrogen react in the presence of an iron catalyst to form ammonia. The hydrogen is formed by reacting natural gas and steam at high temperatures and the nitrogen is supplied from the air 1.-Chemicals-A-Ammonia and Urea-9 into the secondary urea reactor. The excess ammonia is condensed and used as feedstock to the primary reactor. Water recycling Evaporated water from the concentration step is used during the third stage of decomposition as the initial recycle solution.
