Abstract

Alternate RF testing is a very promising candidate for replacing the costly standard specification-based approach. The defect filter in the alternate test flow is a crucial preparatory step for the overall success of alternate test. In this paper, we present a novel nonlinear defect filter based on an estimate of the joint probability density function of the alternate measurements. The construction of the filter does not require a defect dictionary and can accommodate any underlying density without needing any prior knowledge regarding its parametric form.
