  • Publication number: 20070077724
    Abstract: Methods and apparatus for etching substrates such as silicon wafers are provided. In one specific approach, a surface of the substrate assembly is covered with a resist that is patterned to define features to be etched. In this approach, the surface is then exposed to a plasma in a plasma etcher so that surface areas not covered with the resist are etched, while the thickness of the resist increases or etches at a rate that is at least ten times slower than that of the exposed areas of the surface. This etching process can be followed with a conventional plasma etch. By combining the etching that increases the resist thickness with the conventional etching of resist in which the resist thins during etching, features having high-aspect-ratios can be etched.

  • Publication number: 20060186087
    Abstract: A method of anisotropically etching a semiconductive substrate uses a hydrofluorocarbon etch gas with an etch selectivity fluorocarbon gas. The fluorocarbon gas is used under conditions that enhance selectivity of the etch to an etch stop layer with respect to a bulk dielectric material such as doped or undoped silicon dioxide. In one method, a silicon dioxide dielectric layer is provided upon an etch stop layer, wherein the etch stop layer comprises silicon dioxide that is doped differently from the silicon dioxide dielectric layer. A gaseous etchant including a hydrofluorocarbon etch gas and a fluorocarbon selectivity compound is provided, and the silicon dioxide dielectric layer is exposed to the gaseous etchant.

  • Publication number: 20060154483
    Abstract: In a copper plating process, a seed layer is uniformly deposited over a surface, including lining a high aspect ratio trench defined by that surface. A mask layer is provided using a process that fails to deposit in the trench. In one exemplary embodiment, the failure is due to the decrease in the isotropic flux of neutrals toward the bottom of the trench. Copper is subsequently electroplated. Because the seed layer is exposed only within the trench, copper deposits only therein. The self-aligned mask prevents plating outside of the trench. A chemical-mechanical planarization step removes the mask and the seed layer extending beyond the trench, leaving a copper structure within the trench. The structure may serve as a conductive line, an interconnect, or a capacitor plate.

  • Publication number: 20060105577
    Abstract: A modulated bias power etching method for etching a substrate is disclosed. The method alternatively deposits and etches material from a low aspect area of an integrated circuit device to form a static area while etching material from a high aspect area. The modulation pulse period and repetition rate are adjusted to permit deposition at low aspect ratio and very little or no deposition at high aspect ratio during the deposition cycle and to permit etching of the material deposited on the low aspect ratio area and etching of the material in the high aspect ratio area during the etching cycle.

  • Publication number: 20060021969
    Abstract: A plasma process reactor and method is disclosed that allows for greater control in varying the functional temperature range for enhancing semiconductor processing and reactor cleaning. The temperature is controlled by splitting the process gas flow from a single gas manifold that injects the process gas behind the gas distribution plate into two streams where the first stream goes behind the gas distribution plate and the second stream is injected directly into the chamber. By decreasing the fraction of flow that is injected behind the gas distribution plate, the temperature of the gas distribution plate can be increased. The increasing of the temperature of the gas distribution plate results in higher O2 plasma removal rates of deposited material from the gas distribution plate. Additionally, the higher plasma temperature aids other processes that only operate at elevated temperatures not possible in a fixed temperature reactor.

  • Publication number: 20050206003
    Abstract: In one aspect, the invention encompasses a semiconductor processing method of forming a material over an uneven surface topology. A substrate having an uneven surface topology is provided. The uneven surface topology comprises a valley between a pair of outwardly projecting features. A layer of material is formed over the uneven surface topology. The layer comprises outwardly projecting portions over the outwardly projecting features of the surface topology and has a gap over the valley. The layer is etched, and the etching forms protective material within the gap while removing an outermost surface of the layer. The etching substantially does not remove the material from the bottom of the gap. In another aspect, the invention encompasses a semiconductor processing method of forming a material over metal-comprising lines. A first insulative material substrate is provided. A pair of spaced metal-comprising lines are formed over the substrate.

  • Publication number: 20050173376
    Abstract: This invention is a hardware modification which permits greater uniformity of etching to be achieved in a high-density-source plasma reactor (i.e., one which uses a remote source to generate a plasma, and which also uses high-frequency bias power on the wafer chuck). The invention addresses the uniformity problem which arises as the result of nonuniform power coupling between the wafer and the walls of the etch chamber. The solution to greatly mitigate the nonuniformity problem is to increase the impedance between the wafer and the chamber walls. This may be accomplished by placing a cylindrical dielectric wall around the wafer. Quartz is a dielectric material that is ideal for the cylindrical wall if silicon is to be etched selectively with respect to silicon dioxide, as quartz it is virtually inert under such conditions.

  • Publication number: 20050032388
    Abstract: Plasma etching processes using a plasma containing fluorine as well as bromine and/or iodine are suited for high aspect ratio etching of trenches, contact holes or other apertures in silicon oxide materials. The plasma is produced using at least one fluorine-containing source gas and at least one bromine- or iodine-containing source gas. Bromine/iodine components of the plasma protect the aperture sidewalls from lateral attack by free fluorine, thus advantageously reducing a tendency for bowing of the sidewalls. Ion bombardment suppresses absorption of bromine/iodine components on the etch front, thus facilitating advancement of the etch front without significantly impacting taper.

  • Publication number: 20050022935
    Abstract: A plasma reactor comprises an electromagnetic energy source coupled to a radiator through first and second variable impedance networks. The plasma reactor includes a chamber having a dielectric window that is proximate to the radiator. A shield is positioned between the radiator and the dielectric window. The shield substantially covers a surface of the radiator near the dielectric window. A portion of the radiator that is not covered by the shield is proximate to a conductive wall of the chamber. Plasma reactor operation includes the following steps. A plasma is ignited in a chamber with substantially capacitive electric energy coupled from the radiator. A variable impedance network is tuned so that the capacitive electric energy coupled into the chamber is diminished. The plasma is then powered with substantially magnetic energy.
