silicon wafer Lapping refers to the process of grinding the Si wafer surface so as to remove the damaged layer caused by slicing process and to obtain Si

silicon wafer The charged crucible is electrically heated to a temperature sufficient to melt the polysilicon Once the silicon charge is fully melted, Silicon wafers are generally not 100% pure silicon, but are instead formed with an initial impurity doping concentration between 1013 and 1016 atoms per cm3 of
