When we look at the substrates or chips of semiconductor silicon or other types of materials, we often see technical indicators such as TTV, BOW, WARP, and perhaps even TIR, STIR, LTV, etc. What parameters do they represent?
TTV — Total Thickness Variation, Total Thickness Variation
BOW, b...
A wafer is a thin piece of silicon about a millimeter thick that has a very high degree of flatness on the surface due to the very high requirements of the manufacturing process. The specific application of a wafer determines the type of wafer length required. For example, after polysilicon melts...
