摘要： An interconnect structure and fabrication method are provided to form air gaps between interconnect lines and between interconnect layers. A conductive material is deposited and patterned to form a first level of interconnect lines. A first dielectric layer is deposited over the first level of interconnect lines. One or more air gaps are formed in the first dielectric layer to reduce inter-layer capacitance, intra-layer capacitance or both inter-layer and intra-layer capacitance. At least one support pillar remains in the first dielectric layer to promote mechanical strength and thermal conductivity. A sealing layer is deposited over the first insulative layer to seal the air gaps. Via holes are patterned and etched through the sealing layer and the first dielectric layer. A conductive material is deposited to fill the via holes and form conductive plugs therein. Thereafter, a conductive material is deposited and patterned to form a second level of interconnect lines.

摘要： A damascene interconnect that reduces interconnect intra-layer capacitance and/or inter-layer capacitance is provided. The damascene interconnect structure has air gaps between metal lines and/or metal layers. The interconnect structure is fabricated to a via level through a processing step prior to forming contact vias, then one or more air gaps are formed into the damascene structure so that the air gaps are positioned between selected metal lines. A sealing layer is then deposited over the damascene structure to seal the air gaps.

摘要： An apparatus for channel interleaving comprises a spatial birefringent device assembly and a reflector which is configured so as to direct light from the spatial birefringent device assembly back through the spatial birefringent device assembly. The spatial birefringent device assembly comprises at least one spatial birefringent device. Directing light from the spatial birefringent device assembly back through the spatial birefringent device assembly substantially mitigates cross-talk and/or dispersion of the apparatus for channel interleaving in communications.

摘要： A semiconductor process and structure is provided for use in single or dual damascene metallization processes. A thin metal layer which serves as an etch stop and masking layer is deposited upon a first dielectric layer. Then, a second dielectric layer is deposited upon the thin metallization masking layer. The thin metallization masking layer provides an etch stop to form the bottom of the in-laid conductor grooves. In a dual damascene process, the thin metallization masking layer leaves open the via regions. Thus, the conductor grooves above the metallization masking layer and the via regions may be etched in the first and second dielectric in one step. In a single damascene process, the thin metallization etch masking layer may cover the via regions. The etch stop and masking layer can be formed from any conductive or non-conductive materials whose chemical, mechanical, thermal and electrical properties are compatible with the process and circuit performance.

摘要： Method for fabrication of on-chip inductors and related structure are disclosed. According to one embodiment, inductors are formed by patterning conductors within a certain dielectric layer in a semiconductor die. Thereafter, the entire dielectric layer in the semiconductor die is subjected to a blanket implantation or sputtering of high permeability material. According to another embodiment, a first area in a semiconductor die is covered, for example, with photoresist. A second area in the semiconductor die includes a patterned conductor which is to be used as an inductor. The patterned conductor is also covered, for example, with photoresist. The second area, excluding the covered patterned conductor is subjected to implantation or sputtering of high permeability material. According to yet another embodiment, a first area of a semiconductor die is covered, for example, with photoresist. A second area in the semiconductor area includes a patterned conductor which is to be used as an inductor. This second area, including the patterned conductor, is subjected to implantation or sputtering of high permeability material. The implantation or sputtering of high permeability materials result in the inductors having much higher inductance values than they would otherwise have.

摘要： Method for dual damascene metallization of semiconductor workpieces which uses a process for creating an etch stop in an insulator thereby eliminating the need for deposition of an etch stop layer. Electron beam exposure is used to cure the insulator, or material having a low dielectric constant. Application of the electron beam to the low dielectric constant material converts the topmost layer of the low dielectric constant material to an etch stop layer, while rapid thermal heating cures the remainder of the low dielectric constant material. Creation of an etch stop layer in the low dielectric constant material can also be achieved by curing the low dielectric constant material using ion implantation.

摘要： Methods and structures are disclosed for advanced interconnects in sub-micron and sub-half-micron integrated circuit devices fabricated using a single damascene process. a dielectric etch-stop layer (e.g., silicon nitride) is deposited subsequent to rather than prior to CMP processing of the previous metallization layer (e.g., the conductive plug). This scheme effectively eliminates the effect of CMP-induced erosion on the etch-stop layer and therefore allows an extremely thin etch stop to be used. Moreover, a high etch-selectivity can be obtained for the trench etch, and all etch-stop material is removed from beneath the interconnect metal, thereby reducing parasitic effects. A patterned dielectric layer is used as a metal cap in place of the standard blanket silicon nitride layer, thus preventing the formation of blisters and bubbles associated with trapped moisture and gasses, and reducing interconnect capacitance.

摘要： Systems and methods for a readiness dialog box for a call over network (CON) are provided. In some embodiments, the readiness dialog box is presented to the callers prior to the onset of the call. It presents the other participant's and their status. For example, it may indicate which participants are online, but not yet ready, those who are ready, and those not available. It also enables the caller to send messages (both preconfigured and customized) to the other participants. Once sufficient participants have joined, the call may start. Sufficiency of participants could include a quorum of individuals, may require that specific participants are ready, everyone is ready, or may be time dependent. The participant requirements may be configured by the individual setting up the call based upon call type.
