Die Per Wafer Formula
The following formula is used to calculate the die per wafer.
DFW = d * pi * ( 4/(4*S) – 1/SQRT (2*S) )
- Where DFW is the die per wafer
- d is the diameter of the wafer
- S is the die size (square)
Die Per Wafer Definition
A die per wafer is defined as the number of dies per wafer area of a die-cut part usually square silicon pieces.
