    摘要： A system and method are disclosed for processing an organic memory cell. An exemplary system can employ an enclosed processing chamber, a passive layer formation component operative to form a passive layer on a first electrode, and an organic semiconductor layer formation component operative to form an organic semiconductor layer on the passive layer. A wafer substrate is not needed to transfer from a passive layer formation system to an organic semiconductor layer formation system. The passive layer is not exposed to air after formation of the passive layer and before formation of the organic semiconductor layer. As a result, conductive impurities caused by the exposure to air do not occur in the thin film layer, thus improving productivity, quality, and reliability of organic memory devices. The system can further employ a second electrode formation component operative to form a second electrode on the organic semiconductor layer.

    摘要： Insulating material is formed to surround interconnect structures of an integrated circuit. A first semiconductor wafer is placed in a reaction chamber for forming the insulating material surrounding the interconnect structures of the integrated circuit on the first semiconductor wafer. A corrosive dielectric material having low dielectric constant is deposited to surround the interconnect structures, and the corrosive dielectric material fills any gaps between the interconnect structures. Deposition of the corrosive dielectric material is performed within the reaction chamber, and the corrosive dielectric material is deposited on the reaction chamber during deposition of the corrosive dielectric material on the first semiconductor wafer. An encapsulating layer is formed over the corrosive dielectric material on the first semiconductor wafer and on the reaction chamber to prevent contact of the corrosive dielectric material to any exposed structure of a second semiconductor wafer to be subsequently placed into the reaction chamber when such an exposed structure is reactive with the corrosive dielectric material.

    摘要： The present invention provides a method for selectively removing anti-reflective coating (ARC) from the surface of an dielectric layer over the surface of a substrate without scratching the dielectric layer and/or tungsten contacts formed therein. In one embodiment, a fluoromethane (CH3F)/oxygen (O2) etch chemistry is used to selectively remove the ARC layer without scratching and/or degradation of the dielectric layer, source/drain regions formed over the substrate, and a silicide layer formed atop stacked gate structures. The CH3F/O2 etch chemistry etches the ARC layer at a rate which is significantly faster than the etch rates of the dielectric layer, the source/drain regions and the silicide layer. In addition, by removing the ARC layer prior to the formation of tungsten contacts by filling of contact openings formed in the dielectric layer with tungsten, potential scratching of tungsten contacts due to ARC layer removal is eliminated.

    摘要： In a method for forming an interlayer dielectric (ILD) coating on microcircuit interconnect lines of a substrate, the substrate and interconnect lines are annealed prior to deposition of an ILD. A post annealing SiON layer is formed by using plasma-enhanced chemical vapor deposition. The deposition using a plasma formed of nitrogen, nitrous oxide, and silane gases, with the gases being dispensed at regulated flow rates and being energized by a radio frequency power source. The plasma reacts to form SiON which is deposited on a semiconductor substrate. Additionally, during deposition, minor adjustments are made to deposition temperature and process pressure to control the optical characteristics of the SiON layer. The SiON layer is tested for acceptable optical properties and acceptable SiON layers are coated with a SiO2 layer to complete formation of the ILD. Once the ILD is formed the substrate is in readiness for further processing. The pre-ILD annealing results in a substantially reduced incidence of stress-induced voiding in the underlying interconnect lines. Furthermore, the pre-ILD annealing can be combined with other advantageous process environments to more significantly reduce the incidence of stress-induced voiding in the underlying interconnect lines. Such combinations include process temperature reduction to below about 380 degrees Celsius and reduction of silane flow rate to less than about sixty standard cubic centimeters per minute.

    摘要： An integrated circuit and manufacturing method therefor is provided having a semiconductor substrate with a semiconductor device and a device dielectric layer formed on the semiconductor substrate. A channel dielectric layer on the device dielectric layer has a channel opening, an alloy-barrier layer lining the channel opening, and a conductor core filling the channel opening. An alloy layer is deposited which contains an element capable of reacting during thermal treatment with both the conductor core and the channel dielectric layer to form an alloy-barrier to diffusion of the material of the conductor core to the channel dielectric layer. The alloy-barrier layer is reacted with the conductor core and the channel dielectric layer to form a compound which provides a bond which blocks surface diffusion and permits conductor core to conductor core diffusion in dual inlaid integrated circuits.

    摘要： Improved dielectric layers are formed by surface treating the dielectric layer with a silane plasma prior to forming a subsequent layer thereon. Embodiments include forming a trench in a low k dielectric layer and modifying the side surfaces of the trench by subjecting the dielectric to a silane plasma produced in a PECVD chamber. A conductive feature is formed by depositing a conformal barrier layer on the low k dielectric including the treated side surfaces of the dielectric and depositing a conductive layer within the trench.
