Abstract: Embodiments of process flows and methods are provided for forming a resistive switching random access memory (ReRAM). More specifically, process flows and methods are provided for reducing the forming voltage needed to form a conductive path in the ReRAM cells. A wide variety of plasma doping processes are used to introduce a plurality of different dopants into a metal-oxide dielectric film. By utilizing at least two different dopants, the plasma doping processes described herein reduce the forming voltage of the subsequently formed ReRAM cell compared to conventional processes that use only one dopant. In some embodiments, the forming voltage may be further reduced by applying a bias power during the plasma doping process, wherein the bias power is preselected to increase the number of ions introduced into the metal-oxide dielectric film during the plasma doping process.

Abstract: A resistive memory device with an embedded shoulder pulled sidewall spacer and method of forming. The method includes providing a patterned film stack containing a lower electrode layer, a dielectric filament layer on the lower electrode layer, and an upper electrode layer on the dielectric filament layer, depositing a conformal cap layer on the patterned film stack, dry etching the conformal cap layer to form a sidewall spacer on sidewalls of the patterned film stack, where a top of the sidewall spacer is recessed to below a top of the upper electrode layer by the dry etching. The method further includes encapsulating the patterned film stack in an isolation layer, and etching the isolation layer to expose the upper electrode layer without exposing the sidewall spacer.

Abstract: A process and device is disclosed for etching a magnetroresistive random access memory device which includes at least one magnetic tunnel junction stack structure which includes an insulating layer disposed between first and second magnetic layers. The process includes the step of contacting a substrate with a chlorine containing plasma at a temperature no greater than 30 degrees Centigrade under conditions effective to convert at least a portion of the first and second magnetic layers and the insulating layer into metal chlorides. Next, the resulting product of the contacting step is treated with an organic solvent under conditions effective to remove the metal chlorides. The treatment can include rinsing away the metal chlorides either by dissolving the metal chlorides, or by reacting the metal chlorides with a reactive organic solvent, or both.

Abstract: A method of forming a semiconductor structure may include forming at least one fin and forming, over a first portion of the at least one fin structure, a gate. Gate spacers may be formed on the sidewalls of the gate, whereby the forming of the spacers creates recessed regions adjacent the sidewalls of the at least one fin. A first epitaxial region is formed that covers both one of the recessed regions and a second portion of the at least one fin, such that the second portion extends outwardly from one of the gate spacers. A first epitaxial layer is formed within the one of the recessed regions by etching the first epitaxial region and the second portion of the at least one fin. A second epitaxial region is formed at a location adjacent one of the spacers and over the first epitaxial layer within one of the recessed regions.
