Silicon is a semiconductor, meaning that it has a high resistance to the flow of electricity, though not as high of a resistance as an "insulator" like rubber. The electrical properties of pure silicon can be manipulated by adding other elements called "dopants" which will determine the type of the silicon either positive or negative, and change the resistivity of the silicon so that it becomes more conductive. The type of dopant will determine whether the final wafer is a P-Type silicon wafer or an N-Type silicon wafer, and the amount of dopant will determine its final resistivity.
P-Type silicon wafers are the most common in terms of production and sales volume. These wafers are manufactured with only one type of dopant called Boron which is referred to as B in the periodic table. How much Boron that is present in a P-Type silicon wafer determines its resistivity; the more Boron that is present then the lower the resistivity while the less Boron that is present then the higher the resistivity. The relative abundance of P-Type silicon wafers tends to keep their cost lower than that of N-Type silicon wafers.
