Enter the wafer diameter and the die size into the calculator to determine the die per wafer.
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 the number of dies per wafer area of a die cut part usually square silicon pieces.
