Computer memory technology is disclosed. In one example, a method for isolating computer memory blocks in a memory array from one another can include forming an opening between adjacent blocks of memory structures. The method can also include forming a protective liner layer on at least the memory structures. The method can further include disposing isolating material in the opening and on the protective liner layer. The method can even further include removing the isolating material on the protective liner layer. The method can additionally include removing the protective liner layer on the memory structures. Associated devices and systems are also disclosed.

Some embodiments include a memory assembly having memory cells proximate a conductive source. Channel material extends along the memory cells and is electrically coupled with the conductive source. The conductive source is over an insulative material and includes an adhesion material directly against the insulative material. The adhesion material comprises one or more of metal, silicon nitride, silicon oxynitride, silicon carbide, metal silicide, metal carbide, metal oxide, metal oxynitride and metal nitride. The conductive source includes metal-containing material over and directly against the adhesion material. The metal-containing material consists essentially of metal. The conductive source includes a metal-and-nitrogen-containing material over and directly against the metal-containing material, and includes a conductively-doped semiconductor material over the metal-and-nitrogen-containing material.

A process for fabricating an MOS device specifically a DRAM device, featuring passivation of defects in regions of a semiconductor substrate wherein defects left unpassivated can deleteriously influence data retention time, has been developed. A high density plasma dry etching procedure used to define the DRAM conductive gate electrode can create unwanted defects in a region near the surface of uncovered portions of the semiconductor substrate during the high density plasma procedure over etch cycle. Implantation of a group V element such as arsenic can be used to passivate the unwanted plasma etch defects, thus reducing the risk of defect related device leakage phenomena. However to insure the group V implanted species remain at or near the semiconductor surface for optimum defect passivation, the group V element implantation procedure is performed after all high temperature DRAM fabrication steps, such as selective oxidation for creation of oxide spacers on the sides of the conductive gate electrode, have been completed. A slow diffusing implanted arsenic ion is the optimum candidate for passivation while faster diffusing group V elements such as phosphorous are not as attractive for defect passivation.
