    摘要: A magneto resistive memory device is fabricated by etching a blanket metal stack comprised of a buffer layer, pinned magnetic layer, a tunnel barrier layer and a free magnetic layer. The problem of junction shorting from resputtered metal during the etching process is eliminated by formation of a protective spacer covering the side of the freelayer and tunnel barrier interface. The spacer is formed following the first etch through the free layer which stops on the barrier layer. After spacer formation a second etch is made to isolate the device. The patterning of the device tunnel junction is made using a disposable mandrel method that enables a self-aligned contact to be made following the completion of the device patterning process.

    摘要: A capacitor electrode is produced with an underlying barrier structure. A barrier incorporation layer is used and a CMP (chemical mechanical polishing) process is employed in order to produce the barrier structure. The capacitor electrode with an underlying barrier structure is produced by depositing a barrier layer on a semiconductor substrate; forming a barrier structure from the barrier layer with a lithographic mask and an etching step; depositing a barrier incorporation layer covering the barrier structure and surrounding regions; and removing the barrier incorporation layer with chemical mechanical polishing until the barrier structure is uncovered, to thereby form the capacitor electrode above the barrier structure.

    摘要: The invention relates to a microelectronic structure. In the structure, an oxygen-containing iridium layer is embedded between a silicon-containing layer and an oxygen barrier layer. The iridium layer is especially produced by a sputter process in an oxygen atmosphere with a low oxygen content. The oxygen-containing iridium layer is stale at temperatures up to 800° C. and withstands the formation of iridium silicide upon contact with the silicon-containing layer. Such micro-electronic structures are preferably used in semiconductor memories.

    摘要: The invention relates to a method for producing ferroelectric capacitors that are structured using the stack principle and that are used in integrated semiconductor memory chips. The individual capacitor modules have an oxygen barrier between a lower capacitor electrode and an electrically conductive plug. At a site where it is not covered by the corresponding oxygen barrier, an unstructured adhesive layer is oxidized by the oxygen arising during the tempering process of the ferroelectric and forms insulating segments at the site in such a way that the lower capacitor electrodes of the ferroelectric capacitors are electrically insulated from one another. This makes it possible to dispense with structuring the adhesive layer. Furthermore, the layer serves as a getter of oxygen and inhibits the diffusion of oxygen to the plug.
