The multi-resistive state element is sandwiched between the electrodes such that the top face of the bottom electrode is in contact with the multi-resistive state element's bottom face and the bottom face of the top electrode is in contact with the multi-resistive state element's top face. The bottom electrode, the top electrode and the multi-resistive state element all have sides that are adjacent to their faces. Furthermore, the sides are at least partially covered by a sidewall layer.

Abstract: A conductive memory stack is provided. The memory stack includes a bottom electrode, a top electrode and a multi-resistive state element that is sandwiched between the electrodes. The bottom electrode can be described as having a top face with a first surface area, the top electrode has a bottom face with a second surface area and the multi-resistive state element has a bottom face with a third surface area and a top face with a fourth surface area. The multi-resistive state element's bottom face is in contact with the bottom electrode's top face and the multi-resistive state element's top face is in contact with the top electrode's bottom face. Furthermore, the fourth surface area is not equal to the second surface area.

Abstract: Multiple modes of operation in a cross point array. The invention is a cross point array that uses a read voltage across a conductive array line pair during a read mode. The read voltage produces a read current that is indicative of a first program state when the read current is at a first level and indicative of a second program state when the read current is at a second level. The read current is ineffective to produce a change in program state. A first voltage pulse is used during a first write mode if a change from a second program state to a first program state is desired. A second voltage pulse is used during a second write mode if a change from the first program state to the second program state is desired.

Abstract: A method to simplify the polycide gate structure fabrication processes by using a hardmask 240 to define a pattern of siliciding 260 a silicon layer 230, and then using the silicide 260 to mask removal of the unreacted silicon 220 and 230 in locations where the hardmask 240 had been present. The metal silicide 260 formed in the exposed silicon regions 220 and 230 functions as a self-aligned mask against the silicon 220 and 230 etching. By using a selective etching process between the silicon 220 and 230 and the silicide 260, the silicon 220 and 230 can be etched down to the gate oxide 210 to form the polycide (silicide/polysilicon) gate. The polycide gate formed by this method is particularly advantageous in DRAM applications, but can also be used as a MOS gate in a transistor.

Abstract: A process for fabricating a trench filled with an insulating material in a surface of an integrated circuit substrate is described. One step of the process includes defining a masking layer on a composite layered stack above a region to be protected on the integrated circuit substrate surface. The composite layered stack includes a layer of a first material and a polishing stopping layer. The layer of the first material has a polishing rate by chemical mechanical polishing that is greater than a polishing rate by chemical mechanical polishing of the insulating material. Another step of the process includes etching through the composite layered stack and the integrated circuit substrate to form the trench in the integrated circuit substrate surface and depositing the insulating material on the integrated circuit substrate surface such that the trench is filled with the insulating material.

Abstract: A method for forming a ultra-shallow junction region (104). A silicon film (single crystalline, polycrystalline or amorphous) is deposited on the substrate (100) to form an elevated S/D (106). A metal film is deposited over the silicon film and reacted with the silicon film to form a silicide film (108). The silicon film is preferably completely consumed by the silicide film formation. An implant is performed to implant the desired dopant either into the metal film prior to silicide formation or into the silicide film after silicide formation. A high temperature anneal is used to drive the dopant out of the silicide film to form the junction regions (104) having a depth in the substrate (100) less than 200 Å. This high temperature anneal may be one of the anneals that are part of the silicide process or it may be an additional process step.

Abstract: A process is disclosed for forming vias and trenches in two separate dielectric layers, which may be separated by an etch stop, while avoiding the etch mask stress complicated resist masks, or high aspect ratio openings of the prior art. A first dielectric layer 10 is formed over an integrated circuit structure 2 on a semiconductor substrate, and a thin second dielectric layer 20 is formed over the first dielectric layer. A first resist mask, is formed over the second dielectric layer, and the first and second dielectric layers are etched through to form one or more vias 18, 28 extending through both the first and second dielectric layers. The first resist mask is then removed and a third dielectric layer 70, having different etch characteristics than the second dielectric layer, is deposited over the structure.
