Yield D0 Die Calculator

1. Yield to Poisson D0 and BE DD
Yield = % input yield number
Chip Area = cm 2 input chip area
Poisson D0 = 1/cm 2
Complexity Factor = default complexity factor for each process node can be found at ARIMA model section below
Product Pre-factor = default = 1
k-Factor default = 1
BE DD = 1/inch 2
Calculate
2. Poisson D0 → BE DD
Poisson D0 = 1/cm 2 input Poisson D0 for conversion

Technology Node
(Poisson) Df 1/cm 2 Saturated Poisson D0. Typically < 0.1/cm 2
ARIMA LR % Monthly reduction of Poisson D0.
Industry average is 91-93% (7-9% reduction per month), and PDF can help customer double the learning (14 - 18% reduction per month, or LR = 82 - 86%). ( see more)
