P type We specialize in silicon wafers largest suppliers and producer of the p type silicon wafer. We are also able to also customised the p type silicon wafer in line in collaboration with the customers requiement. The sand is heated to about 1600 degrees c just above its melting pointa pure silicon seed crystal is placed into the molten sand baththe seed is pulled out slowly as it stands rotatedthe result is a pure silicon cylinder an ingotthe ingot is sliced into very thin waferswafers are polished until they are very smooth and just the right thickness technical specification should contain boron as a dopanttype Featuring this polished, Semiconductor properties surface has a diameter of 3 inches and a thickness of 0. 5 mm on one side orientation resistivity < 10 o, Cm
