A microelectronic element such as a chip or microelectronic wiring substrate is provided which includes a plurality of conductive interconnects for improved resistance to thermal stress. At least some of the conductive interconnects include a metallic plate, a metallic connecting line and an upper metallic via. The metallic connecting line has an upper surface at least substantially level with an upper surface of the metallic plate, an inner end connected to the metallic plate at one of the peripheral edges, and an outer end horizontally displaced from the one peripheral edge. The metallic connecting line has a width much smaller than the width of the one peripheral edge of the metallic plate and has length greater than the width of the one peripheral edge. The upper metallic via has a bottom end in contact with the metallic connecting line at a location that is horizontally displaced from the one peripheral edge by at least about 3 microns (μm).
摘要:
A novel interlevel contact via structure having low contact resistance and improved reliability, and method of forming the contact via. The method comprises steps of: etching an opening through an interlevel dielectric layer to expose an underlying metal (Copper) layer surface; and, performing a low energy ion implant of an inert gas (Nitrogen) into the exposed metal underneath; and, depositing a refractory liner into the walls and bottom via structure which will have a lower contact resistance due to the presence of the proceeding inert gas implantation. Preferably, the inert Nitrogen gas reacts with the underlying exposed Copper metal to form a thin layer of CuN.

Gate conductors on an integrated circuit are formed with enlarged upper portions which are utilized to electrically connect the gate conductors with other devices. A semiconductor device comprises a gate conductor with an enlarged upper portion which electrically connects the gate conductor to a local diffusion region. Another semiconductor device comprises two gate conductors with enlarged upper portions which merge to create electrically interconnected gate conductors. Methods for forming the above semiconductor devices are also described and claimed.

A hardmask layer in the back end of an integrated circuit is formed from TaN having a composition of less than 50% Ta and a resistivity greater than 400 μOhm-cm, so that it is substantially transparent in the visible and permits visual alignment of upper and lower alignment marks through the hardmask and intervening layer(s) of ILD. A preferred method of formation of the hardmask is by sputter deposition of Ta in an ambient containing N2 and a flow rate such that (N2 flow)/(N2+carrier flow)>0.5.

摘要:
A method and structure for an electrode device, whereby a second electrode is deposited on a first electrode such that there is an increase in the capacitive coupling between the pair of conductive electrodes. The electrodes are self-aligning such that the patterning manufacturing process is insensitive to variations in the positional placement of the pattern on the substrate. Moreover, a single lithographic masking layer is used for forming the pair of electrodes, which are electrically isolated. Finally, the first electrode is offset from the second electrode by a chemical surface modification of the first electrode, and an anisotropic deposition of the second electrode which is shadowed by the first electrode.

A method and structure for an improved DRAM (dynamic random access memory) dielectric structure, whereby a new high-k material is implemented for both the support devices used as the gate dielectric as well as the capacitor dielectric. The method forms both deep isolated trench regions used for capacitor devices, and shallow isolated trench regions for support devices. The method also forms two different insulator layers, where one insulator layer with a uniform high-k dielectric constant is used for the deep trench regions and the support regions. The other insulator layer is used in the array regions in between the shallow trench regions.

A semiconductor structure includes a diamond-like carbon layer as a polish-stop for patterning a metal level into an inter-level dielectric substrate in a damascene process flow. The semiconductor structure includes a substrate having a dielectric layer followed by the diamond-like carbon layer on a surface thereof. The diamond-like carbon layer is used as a hard-mask for forming conductive metal features from grown substrate material that fills a plurality of openings in the substrate, therein forming a semiconductor island structure, The semiconductor structure has a planar surface at the diamond-like carbon layer and the grown substrate material, whereby the diamond-like carbon polish-stop layer allows for over-planarization of the semiconductor island structure to provide an improved planar surface having a sufficient decrease in topography.
