Test structures have been designed to detect the impact of field enhancement on low-k dielectric breakdown at the tips of combs in comb structures. An analysis methodology has been proposed to separate the impact of area and field enhancement. Modeling utilizes characteristic lifetimes at various area ratios. The proposed model, when compared with direct fitting of the Weibull distribution, improves...
We report the experimental study of field emission from cold cathodes having a raised ridge or knife-edge structure and analyses using a Transfer Matrix Method (TMM) model used to extract the cathode parameters. Local emission current measurements were done on a copper cathode, which was fabricated using electric discharge machining (EDM) and chemical etching yielding ridges of thickness 15 mum. Measurements...
