    摘要: A method for insitu performing a cleaning operation along with a physical sputtering operation begins by placing a wafer (26) into a chamber (12). A plasma (30) is generated within the chamber (12) using an inert, noble, or reducing gas. The gas is ionized to form ions (32) within the plasma (30). Power is provided to various components (16, 22, and 24) within the chamber (12) to ensure that the ions (32) are accelerated towards the wafer (26) during first stages of wafer processing. This acceleration of the ions (32) towards the wafer (26) will clean a surface of the wafer (26). Following this cleaning operation, power supplied within the chamber (12) is altered to accelerate the ions (32) into a reverse direction so that the ions (32) impact a sputter target (20). Due to ionic bombardment of the target (20), a material is sputtered onto a clean surface of the wafer (26) in an insitu manner.

    摘要: A method for depositing a first metal layer such as tantalum or copper on a patterned semiconductor wafer using a metal sputtering tool that typically includes an electrically biased wafer chuck is disclosed. Initially, a first test wafer is placed on the wafer chuck and a first test layer of materials is deposited on the first test wafer. During the deposition of the first test layer on the first test wafer, the wafer receives the electrical bias at a first level. A second test wafer is then placed on the wafer chuck and a second test layer of material is deposited with the second wafer receiving a second level of electrical bias. The difference in thickness between the first layer and the second layer is then determined. If the difference in thickness is within a predetermined range, the metal sputtering chamber is qualified to deposit a production layer on a production semiconductor wafer.

    摘要: The formation of an adhesion/interlayer region (410) of a semiconductor substrate device (404) before barrier layer (412) deposition provides improved adhesion of the barrier layer (412) to the underlying dielectric (404) and increases strength to the next interconnect layer without altering the function of the barrier layer (412) to limit Cu diffusion into the dielectric substrate (404). The adhesion/interlayer region (410) is formed in an inlaid structure (400, 500) of a semiconductor wafer. The inlaid structure (400, 500) is connected to upper or lower metal layers through vias in the dielectric layer (404) to a copper layer. The adhesion/interlayer region is formed by flowing a treating gas in a glow discharge process of the dielectric substrate in a chamber either attached or separated from the barrier deposition chamber (300). The barrier layer (412) and the adhesion/interlayer region (410) can be formed in this inlaid structure (400, 500) of a semiconductor wafer. The treating gas (212, 320) can be nitrogen, hydrogen, gases containing carbon atoms, or some other suitable gas.

    摘要: A process for manufacturing semiconductors uses an enclosure (22) having an interior surface-that is intentionally-roughened by spraying quartz (44) onto the interior surface. The sprayed quartz (44) creates additional surface area for the purpose of trapping or capturing etched material in the enclosure during the process. The roughness of the interior surface is not significantly reduced during the semiconductor processing so that only chemical cleaning is required to maintain the interior surface for long-term use.

    摘要: A semiconductor device comprises a substrate (100), first conductive film (22 and 32) over the substrate (100), and a second conductive film (54 and 64) over the first conductive film (22 and 32). The first conductive film includes a refractory metal and nitrogen. The first conductive film has a first portion (22) that lies closer to the substrate and a second portion (32) that lies further from the substrate. The nitrogen percentage for the second portion (32) is lower than the nitrogen atomic percentage for the first portion (22). The second conductive film (54 and 64) includes mostly copper. The combination of portions (22 and 32) within the first conductive film provides a good diffusion barrier (first portion) and has good adhesion (second portion) with the second conductive film (54 and 64).
