  • Publication number: 20060292863
    Abstract: Methods are disclosed for metal encapsulation for preventing exposure of metal during semiconductor processing. In one embodiment, the method includes forming an opening in a structure exposing a metal surface in a bottom of the opening, where the opening forming step occurs in a tool including at least one clustered chamber. An at least partially sacrificial encapsulation layer is then formed on the exposed metal surface in the tool to prevent reaction of the exposed metal surface with the ambient. Exposure of the metal is thereby prevented.

  • Publication number: 20060249850
    Abstract: A ground shield is disclosed that includes a ‘cheesed’ metal positioned within a dielectric layer and a metal region positioned within a first metal level over the cheesed metal. The ground shield can have different forms depending on the metal used, and provisions are made to prevent diffusion of copper (Cu) when that is used as the metal in the cheese metal of the ground shield. The ground shield provides a low resistance, very thick metal at a first metal (M1) level for passive RF elements in conjunction with the standard back-end-of-line (BEOL) integration. The invention also includes a method of forming the ground shield.

  • Publication number: 20060195809
    Abstract: A circuit layout methology is provided for eliminating the extra processing time and file-space requirements associated with the optical proximity correction (OPC) of a VLSI design. The methodology starts with the design rules for a given manufacturing technology and establishes a new set of layer-specific grid values. A layout obeying these new grid requirements leads to a significant reduction in data preparation time, cost, and file size. A layout-migration tool can be used to modify an existing layout in order to enforce the new grid requirements.

  • Publication number: 20060163706
    Abstract: A method for connecting a microelectronic device to a wirebond comprises providing a substrate having a microelectronic circuit therein and forming a wiring layer over the substrate. The wiring layer includes a bilayer wiring structure comprising upper and lower electrically conductive layers separated by a protective electrically conductive layer. The lower layer of the bilayer structure is at the level of the wiring layer and the upper layer of the bilayer structure extends above the level of the wiring layer. The bilayer wiring structure is formed by depositing the upper and lower electrically conductive layers separated by a protective electrically conductive layer over the substrate, etching the upper electrically conductive layer and a portion of the protective electrically conductive layer, and thereafter separately etching the lower electrically conductive layer to form the wiring layer over the substrate. The method also includes connecting a wirebond to the upper layer of the bilayer structure.

  • Publication number: 20060152333
    Abstract: A resistor with heat sink is provided. The heat sink includes a conductive path having metal or other thermal conductor having a high thermal conductivity. To avoid shorting the electrical resistor to ground with the thermal conductor, a thin layer of high thermal conductivity electrical insulator is interposed between the thermal conductor and the body of the resistor. Accordingly, a resistor can carry large amounts of current because the high conductivity thermal conductor will conduct heat away from the resistor to a heat sink. Various configurations of thermal conductors and heat sinks are provided offering good thermal conductive properties in addition to reduced parasitic capacitances and other parasitic electrical effects, which would reduce the high frequency response of the electrical resistor.

  • Publication number: 20060138480
    Abstract: An image sensor and method of fabrication wherein the sensor includes Copper (Cu) metallization levels allowing for incorporation of a thinner interlevel dielectric stack to result in a pixel array exhibiting increased light sensitivity. The image sensor includes structures having a minimum thickness of barrier layer metal that traverses the optical path of each pixel in the sensor array or, that have portions of barrier layer metal selectively removed from the optical paths of each pixel, thereby minimizing reflectance. That is, by implementing various block or single mask methodologies, portions of the barrier layer metal are completely removed at locations of the optical path for each pixel in the array. In a further embodiment, the barrier metal layer may be formed atop the Cu metallization by a self-aligned deposition.

  • Publication number: 20060113622
    Abstract: An image sensor array and method of fabrication wherein the sensor includes Copper (Cu) metallization levels allowing for incorporation of a thinner interlevel dielectric stack with improved thickness uniformity to result in a pixel array exhibiting increased light sensitivity. In the sensor array, each Cu metallization level includes a Cu metal wire structure formed at locations between each array pixel and, a barrier material layer is formed on top each Cu metal wire structure that traverses the pixel optical path. By implementing a single mask or self-aligned mask methodology, a single etch is conducted to completely remove the interlevel dielectric and barrier layers that traverse the optical path. The etched opening is then refilled with dielectric material.

  • Publication number: 20060027929
    Abstract: Methods and structures having pore-closing layers for closing exposed pores in a patterned porous low-k dielectric layer, and optionally a reactive liner on the low-k dielectric. A first reactant is absorbed or retained in exposed pores in the patterned dielectric layer and then a second reactant is introduced into openings such that it enters the exposed-pores, while first reactant molecules are simultaneously being outgassed. The second reactant reacts in-situ with the outgassed first reactant molecules at a mouth region of the exposed pores to form the pore-closing layer across the mouth region of exposed pores, while retaining a portion of each pore's porosity to maintain characteristics and properties of the porous low-k dielectric layer. Optionally, the first reactant may be adsorbed onto the low-k dielectric such that upon introduction of the second reactant Into the patterned dielectric openings, a reactive liner is also formed on the low-k dielectric.

  • Publication number: 20060027930
    Abstract: Improved mechanical and adhesive strength and resistance to breakage of copper integrated circuit interconnections is obtained by forming a copper alloy in a copper via/wiring connection in an integrated circuit while minimizing adverse electrical effects of the alloy by confining the alloy to an interfacial region of said via/wiring connection and not elsewhere by a barrier which reduces or substantially eliminates the thickness of alloy in the conduction path. The alloy location and composition are further stabilized by reaction of all available alloying material with copper, copper alloys or other metals and their alloys.
