Abstract: The present invention provides systems and methods that facilitate formation and use of organic memory devices. An electroless plating process is employed that operates at relatively low temperatures and without employing electrical current. The electroless process is utilized to form conductive layers, such as electrodes and the like, from conductive materials. The process includes depositing an activation compound on selected areas and then applying a chemical solution. The chemical solution contains metal ions. Then, a chemical reaction occurs reducing the metal ions and thereby plating the metal ions and forming a conductive layer. Specifically, the electroless process can be employed to form a top electrode of an organic memory device.

Abstract: A method of forming ultra-shallow junctions in a semiconductor wafer forms the gate and source/drain junctions having upper surfaces at first metal suicide regions on the gate and source/drain junctions. These first metal silicide regions have a higher resistivity. Amorphous silicon is deposited on the first metal suicide regions by plasma enhanced chemical vapor deposition (PECVD). The PECVD process may be a lower pressure deposition process, performed at multiple stations to form the amorphous silicon layer in multiple layers. This creates a more uniform amorphous silicon layer across the wafer and different patterning densities, thereby improving device performance and characteristics. Annealing is then performed to form second metal silicide regions of a lower resistivity, by diffusion reaction of the first metal silicide regions and the amorphous silicon that was deposited by the PECVD process.
