Abstract: A process for fabricating non-volatile memory by tilt-angle ion implantation comprises essentially the steps of implanting sideling within a nitride dielectric layer heterogeneous elements such as, for example, Ge, Si, N2, O2, and the like, for forming traps capable of capturing more electrons within the nitride dielectric layer such that electrons can be prevented from binding together as the operation time increased; etching off both ends of the original upper and underlying oxide layers to reduce the structural destruction caused by the implantation of heterogeneous elements; and finally, depositing an oxide gate interstitial wall to eradicate electron loss and hence promote the reliability of the device.

Abstract: A method for forming a conductive region on a first portion of a substrate, the method being constituted by exposing the first portion to a filtered beam of substantially fully ionised metallic ions under a pulsed, modulated electrical bias. The method uses FCVA (Filtered Cathodic Vacuum Arc) techniques to generate the filtered ion beam and permits the formation of a conformal metal coating, even in high aspect ratio visa and trenches. The method also permits the in-filling of vias and trenches to form conductive interconnects. Particular examples concern the deposition of copper ions. An adapted FCVA apparatus deposits metals on substrates. A control apparatus controls ion beams impacting upon substrates, the control apparatus being suitable for incorporation within existing filtered ion beam sources.
