Patent ID: 8839180

Claim:
A computer implemented method for performing a dielectric reliability assessment for an advanced semiconductor, the method comprising: receiving data associated with a test of a macro of the advanced semiconductor to a point of dielectric breakdown; scaling, by a processor, the data for the macro down to a reference area; extracting a parameter for a Weibull distribution from the scaled down data for the reference area; deriving a cluster factor (α) from the scaled down data for the reference area; and projecting a failure rate for a larger area of the advanced semiconductor based on the extracted parameter, the cluster factor and the recorded data associated with the dielectric breakdown of the macro; wherein the projection is made using according to: F 2 = 1 - { 1 + A 2 A 1 ⁢ ( ( 1 - F 1 ) - 1 / α - 1 ) } - α ≅ 1 - ( 1 - F 1 ) A 2 A 1  F 1 ⪡ 1 wherein A 1 is a size of the tested macro, A 2 is the size of the larger area of the advanced semiconductor, F 1 is a cumulative failure of the tested macro, and F 2 is a cumulative failure of the larger area of the advanced semiconductor.
