Yield D0 Die Calculation

1. Yield to Poisson D0 and BE DD
Yield =	%	input yield number
Chip Area =	cm²	input chip area
Poisson D0 =	1/cm²
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/inch²
Calculate
2. Poisson D0 → BE DD
Poisson D0 =	1/cm²	input Poisson D0 for conversion
Chip Area =	cm²	input chip area
Yield =	%
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/inch²
Calculate
3. BE DD → Poisson D0
BE DD =	1/inch²	input BE DD for conversion
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
Chip Area =	cm²	input chip area
Yield =	%
Poisson D0 =	1/cm²
Calculate

Technology Node
(Poisson) Df		1/cm²	Saturated Poisson D0. Typically < 0.1/cm²
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)
Starting Poisson D0		1/cm²
