  • Publication number: 20240129293
    Abstract: Techniques for (i) using contextual information associated with an exposed credential to identify a resource that could be accessed using the exposed credential, (ii) identifying a responsible entity of that resource, and (iii) alerting the responsible entity about the exposed credential are disclosed. A credential is determined to be in an exposed state. The exposed credential, if used, could potentially provide an actor access to a resource, despite the fact that the actor should not have access to the resource. The exposed credential is analyzed to determine a context. Based on that context, the resource is identified. A responsible entity associated with the resource is identified. An alert is then sent to that entity.

  • Patent number: 7279410
    Abstract: A method for forming an inlaid interconnect structure for ICs. The method includes forming an etch stop layer, opening a portion of the etch stop layer on an IC die, forming a dielectric layer and cap layer over the etch stop layer, forming a photoresist pattern, and etching the cap and dielectric to form an opening that is then filled with a conductive material (e.g., metal). The method may further include forming a barrier layer within the opening of the etch stop layer. According to another aspect of the invention, a first and second etch stop layer are formed over the substrate and the second etch stop layer is patterned to define two regions, wherein a second region having the first and second etch stop layers experiences a faster etch rate than the first region. The dielectric layer and cap layers are then deposited over both regions and two via or trench openings are formed therethrough in the regions, respectively.

  • Patent number: 7001840
    Abstract: An interconnect structure is formed with a plurality of layers of a conductive material with a grain boundary between any two adjacent layers of the conductive material. Such grain boundaries between layers of conductive material act as shunt by-pass paths for migration of atoms of the conductive material to minimize migration of atoms of the conductive material along the interface between a dielectric passivation or capping layer and the interconnect structure. When the interconnect structure is a via structure, each of the layers of the conductive material and each of the grain boundary are formed to be perpendicular to a direction of current flow through the via structure. Such grain boundaries formed between the plurality of layers of conductive material in the via structure minimize charge carrier wind-force along the direction of current flow through the via structure to further minimize electromigration failure of the via structure.

  • Patent number: 6872663
    Abstract: A method of processing a semiconductor device is disclosed and comprises patterning a multi-layer photoresist which comprises an imaging layer overlying an underlying layer. The patterning of the resist defines an exposed portion of an underlying process layer. The method further comprises inspecting the patterned multi-layer photoresist for defects and re-working the patterned multi-layer photoresist upon a failed inspection. The re-work process comprises depositing a protection layer over the patterned multi-layer photoresist and over the exposed portion of the underlying process layer. A portion of the protection layer and the imaging layer are then removed in a concurrent manner while leaving a remaining portion of the protection layer covering the exposed portion of the underlying process layer. A remaining portion of the protection layer and the underlying layer are then removed in a concurrent manner and such removal does not adversely impact the process layer.

  • Patent number: 6846749
    Abstract: A method for forming a metal interconnect comprises exposing a dielectric layer to an etch chemistry containing nitrogen-containing compound such as NH3, NF3 or N2O. The nitrogen-containing compound provides selectivity and/or profile control comparable to that provided by N2, while avoiding poisoning of photoresist by embedded N2.

  • Publication number: 20040232552
    Abstract: A dual damascene air gap process reduces the dielectric constant, and extends CVD low-k technology by removing the sacrificial intra-metal dielectric between conductive lines by patterned etching and replacement with lower k material. The void space between the narrowly spaced conductive lines is sealed in by the non-conformal CVD deposition, thereby further reducing the overall capacitance of the dual damascene interconnect formation.

  • Patent number: 6756300
    Abstract: For forming a dual damascene opening within a dielectric material, a via mask material and a trench mask material are formed over the dielectric material. A trench opening is formed through the trench mask material, and a via opening is formed through a via mask patterning material disposed over the via and trench mask materials. The via and trench mask materials exposed through the via opening of the via mask patterning material are etched away, and the via mask patterning material is etched away. A portion of the dielectric material exposed through the via opening is etched down to the underlying interconnect structure, and a portion of the dielectric material exposed through the trench opening is etched, to form the dual damascene opening.

  • Patent number: 6660619
    Abstract: A method for forming a dual damascene conductive line and conductive plug using porous low k dielectric materials in the via and trench layers. The via layer is provided with dense low k dielectric plugs that increase the mechanical strength of the porous low k dielectric layer that forms the via layer. A via fill technique etches some of the dielectric plugs in the via layer and fills them with conductive material. The via fill technique reduces the damage done to the via holes in the via layer caused by photoresist removal processes.

  • Patent number: 6632707
    Abstract: A method for forming a metal interconnect structure in a semiconductor device with the elimination of via poisoning during trench mask formation employs a CVD organic BARC that isolates the low k dielectric film. The CVD organic BARC is deposited over the low k dielectric film and in the via hole. Once the trench mask has been formed on the CVD organic BARC, the CVD organic BARC may be removed in the same process as the photoresist of the trench mask layer. A properly formed trench will have been created since the via poisoning and resist scumming were substantially eliminated by the presence of the CVD organic BARC.

  • Patent number: 6603206
    Abstract: An interconnect structure and method of forming the same in which a bottom anti-reflective coating/etch stop layer is deposited over a conductive layer. An inorganic low k dielectric material is deposited over the BARC/etch stop layer to form a first dielectric layer. The first dielectric layer is etched to form a slot via in the first dielectric layer. An organic low k dielectric material is deposited within the slot via and over the first dielectric layer to form a second dielectric layer over the slot via and the first dielectric layer. The re-filled via is simultaneously etched with the second dielectric layer in which a trench is formed. The trench extends in a direction that is normal to the length of the slot via. The entire width of the trench is directly over the via. The re-opened via and the trench are filled with a conductive material.
