    摘要: A method and apparatus for forming large scale fields suitable for use in the fabrication of integrated circuit structures having submicron dimensions. The method includes subdividing the large scale field into a plurality of subfields along the boundaries of functional components forming a very large scale integrated circuit. Stitching the subfields into the large scale field is then substantially simplified since the number and dimensions of conductive interconnects between the functional components can be more easily accommodated.

    摘要: An interconnection system having a bottom metal layer that has a conduction layer with a sidewall and an overlying barrier layer. A lateral barrier layer is disposed adjacent the sidewall of the conduction layer, and an insulation layer is over the bottom metal layer. The insulation layer forms vias extending through the insulation layer to the bottom metal layer. A top metal layer extends through the vias to electrically contact the bottom metal layer. The overlying barrier layer and the lateral barrier layer are relatively resistant to interaction with the top metal layer as compared to the conduction layer.

    摘要: A method for producing a relatively thin titanium nitride barrier layer in an integrated circuit is presented. The titanium nitride layer may be utilized in a tungsten plug interconnection by providing a semiconductor wafer with a conducting layer covered by an insulating layer. The insulating layer is patterned and etched to form contact holes or vias. A layer of titanium is deposited on the surface of the wafer including the sidewalls and bottom of the via. A relatively thin titanium nitride layer is then formed on the titanium layer. The formation of the titanium nitride layer includes growing titanium nitride by a reaction of a nitrogen-bearing species with the titanium layer. The titanium nitride layer prevents the underlying titanium layer from reacting with the subsequent tungsten layer which is deposited on the wafer to fill the via. The tungsten layer is then etched so that the tungsten remaining forms a plug interconnection between conducting layers.

    摘要: Remote electrical contacts for a semiconductor are produced by depositing a polysilicon layer over the entire surface of a semiconductor device and removing a portion of the polysilicon layer by chemi-mechanical polishing. The resulting structure is thereby provided with electrically isolated areas of polysilicon which constitute remote electrical contacts for the semiconductor device. The polysilicon layer or the isolated areas of polysilicon can be salicided to provide very low resistivity. Either the polysilicon layer or the salicide layer can be subjected to ion implantation to provide LDD regions.

    摘要: A low k carbon-doped silicon oxide dielectric material dual damascene structure is formed by improvements to a process wherein a first photoresist mask is used to form via openings through a first layer of low k carbon-doped silicon oxide dielectric material, followed by removal of the first photoresist mask; and wherein a second photoresist mask is subsequently used to form trenches in a second layer of low k carbon-doped silicon oxide dielectric material corresponding to a desired pattern of metal interconnects for an integrated circuit structure, followed by removal of the second photoresist mask. The improved process of the invention comprises: forming a first hard mask layer over an upper layer of low k carbon-doped silicon oxide dielectric material previously formed over an etch stop layer formed over a lower layer of low k carbon-doped silicon oxide dielectric material on an integrated circuit structure; forming a first photoresist mask having a pattern of via openings therein over the first hard mask layer; etching the first hard mask layer through the first photoresist mask to form a first hard mask having the pattern of vias openings replicated therein without etching the layers of low k carbon-doped silicon oxide dielectric material beneath the first hard mask; then removing the first photoresist mask; forming a second hard mask layer over the first hard mask; forming a second photoresist mask having a pattern of trench openings therein over the second hard mask layer; etching the second hard mask layer through the second photoresist resist mask to form a second hard mask having the pattern of trench openings replicated therein without etching the layers of low k carbon-doped silicon oxide dielectric material beneath the first and second hard masks; then removing the second photoresist mask; then using the first and second hard masks to respectively form the via openings in the lower layer of low k carbon-doped silicon oxide dielectric material and trench openings in the upper layer of low k carbon-doped silicon oxide dielectric material; whereby a pattern of via openings and a pattern of trench openings can be formed in layers of low k carbon-doped silicon oxide dielectric material without damage to the low k carbon-doped silicon oxide dielectric material during removal of the photoresist masks used respectively in the formation of the pattern of via openings and the pattern of trench openings.

    摘要: A method of performing a characterization of an integrated circuit design that is customized during succeeding fabrication steps. The characterization is accomplished with respect to different levels of a processing parameter that is fixed during preceding fabrication steps. A wafer is processed through the preceding fabrication steps, including processing the wafer at at least one of the preceding fabrication steps using processing that produces the different levels of the processing parameter within different integrated circuits on the wafer. This produces a standardized characterization wafer. The standardized characterization wafer is processed through the succeeding fabrication steps using customized processing to produce a customized characterization wafer. The integrated circuits on the customized characterization wafer are tested to determine which of the different levels of the processing parameter produces integrated circuits having desired characteristics.

    摘要: An apparatus for performing contaminant sensitive processing on a substrate. A substrate load chamber receives the substrate from an ambient contaminant laden environment, and isolates the substrate from the ambient contaminant laden environment. The substrate load chamber further forms a first environment of intermediate cleanliness around the substrate. A substrate pass through chamber receives the substrate from the substrate load chamber, and isolates the substrate from the intermediate cleanliness of the first environment of the substrate load chamber. The substrate pass through chamber further forms a second environment of high cleanliness around the substrate. A substrate transfer chamber receives the substrate from the substrate pass through chamber, and isolates the substrate from the high cleanliness of the second environment of the substrate pass through chamber. The substrate transfer chamber maintains a third environment of high cleanliness around the substrate, and transfers the substrate into more than one substrate processing chambers, where the substrate is selectively transferred into and out of the more than one substrate processing chambers without leaving the high cleanliness of the third environment. The substrate transfer chamber also selectively passes the substrate to the substrate pass through chamber when the substrate pass through chamber has formed the high cleanliness of the second environment. The substrate pass through chamber also receives the substrate from the substrate transfer chamber, and selectively passes the substrate to the substrate load chamber when the substrate load chamber has formed the intermediate cleanliness of the first environment. The substrate load chamber receives the substrate from the substrate pass through chamber, and selectively passes the substrate out of the substrate load chamber and into the ambient contaminant laden environment when the substrate load chamber is not open to the substrate pass through chamber.

    摘要: A double-diffused, lateral transistor structure is fabricated utilizing an etch resistant mask to provide self-aligning positional accuracy for formation of active areas of the transistor. The lateral structure includes semiconductor material having at least one substantially flat surface, and the structure includes at least one region of insulating material formed adjacent the flat surface, the top surface of the insulating material being substantially coplanar with said one surface. A collector is formed in the semiconductor material adjacent first portions of both the flat surface and the insulating material, while an emitter is formed in the semiconductor material adjacent second portions of both the flat surface and the insulating material. A base separates the collector from the emitter.
