The stress-induced voiding (SV) in Al-alloy films with stacked tungsten via structures was investigated. Voids were found in interconnections with stacked and borderless vias that had resistance increase after the aging tests. Failure occurs most fre

A wafer level dielectric breakdown reliability measurement technique using logarithmically stepped-up stress current density is proposed, and the effectiveness of this technique is demonstrated. The stepped current time-dependent dielectric breakdown

The wafer expansion scaling error in overlay accuracy using a stepper has been investigated. The scaling error depends on the exposure energy, mask aperture ratio and wafer surface reflectance. The scaling error is observed only along the X axis when
