  • Patent number: 7074723
    Abstract: We have developed an uncomplicated method of plasma etching deeply recessed features such as deep trenches, of at least 5 ?m in depth, in a silicon-containing substrate, in a manner which generates smooth sidewalls, having a roughness of less than about 1 ?m, typically less than about 500 nm, and even more typically between about 100 nm and 20 nm. Features having a sidewall taper angle, relative to an underlying substrate, typically ranges from about 85° to about 92° and exhibiting the smooth sidewalls are produced by the method. In one embodiment, a stabilizing etchant species is used constantly during the plasma etch process, while at least one other etchant species and at least one polymer depositing species are applied intermittently, typically periodically, relative to each other. In another embodiment, the stabilizing etchant species is used constantly and a mixture of the other etchant species and polymer depositing species is used intermittently.

  • Publication number: 20060148273
    Abstract: Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.

  • Patent number: 7070657
    Abstract: This invention provides a stable process for depositing an antireflective layer. Helium gas is used to lower the deposition rate of plasma-enhanced silane oxide, silane oxynitride, and silane nitride processes. Helium is also used to stabilize the process, so that different films can be deposited. The invention also provides conditions under which process parameters can be controlled to produce antireflective layers with varying optimum refractive index, absorptive index, and thickness for obtaining the desired optical behavior.

  • Patent number: 7072502
    Abstract: A reticle inspection system and method for complete and fast inspection of phase shift mask reticles, both for incoming inspection and for periodic and pre-exposure inspection tool, is employable by facilities such as mask shops as an inspection tool compatible to the mask shop's customers. The inventive system and method detect phase errors in an aerial image by acquiring the image of the phase shift mask under the same optical conditions as the exposure conditions (i.e. wavelength, numerical aperture, sigma, and illumination aperture type). Images are acquired at a positive out-of-focus and a negative out-of-focus, and are compared in order to enhance possible phase error. The term “phase error” refers to the acceptable range of the phase deviation from the programmed 180° on the phase shift mask, by using the exposure system to achieve the image on the photoresist, satisfying the requirements of the wafer specification.

  • Patent number: 7071112
    Abstract: Method, materials and structures are described for the fabrication of dual damascene features in integrated circuits. In via-first dual damascene fabrication, a bottom-antireflective-coating (“BARC”) is commonly deposited into the via and field regions surrounding the via, 107. Subsequent trench etch with conventional etching chemistries typically results in isolated regions of BARC, 107a, surrounded by “fencing” material, 108, at the bottom of the via. Such fencing hinders conformal coating with barrier/adhesion layers and can reduce device yield. The present invention relates to the formation of a BARC plug, 107c, partially filling the via and having a convex upper surface, 400, prior to etching the trench. Such a BARC structure is shown to lead to etching without the formation of fencing and a clean dual damascene structure for subsequent coating.

  • Patent number: 7067399
    Abstract: A method and apparatus for removal of volatile contaminants from substrate surfaces before the substrate enters a process chamber. Substrate cleaning is achieved by irradiating the substrate with a low-energy electron beam. The interaction of the electrons in the beam with the contaminants present on the surface of the substrate causes evaporation of low vapor pressure species which can be deposited on the surface. A cryoshield pumps the evaporated species. After evaporation and pumping, the substrate passes through a glow discharge chamber wherein the negative surface charge created by the electron beam is neutralized using positive ions. The inventive apparatus can be configured so that no separate vacuum chamber is needed to prepare the substrate.

  • Patent number: 7067809
    Abstract: A multi-charged particle beam tool for semiconductor wafer inspection or lithography includes an array of electron beam columns, each having its own electron or ion source. The objective lenses of the various electron beam columns, while each has its own pole piece, share a common single magnetic coil which generates a uniform magnetic field surrounding the entire array of electron beam columns. This advantageously improves the spacing between the beams while providing the superior optical properties of a strong magnetic objective lens. When used as an inspection tool, each column also has its own associated detector to detect secondary and back-scattered electrons from the wafer under inspection. In one version the gun lenses similarly have individual pole pieces for each column and share a common magnetic coil.
