  • Publication number: 20090176350
    Abstract: A method embodiment deposits a first dielectric layer over a transistor and then implants a gettering agent into the first dielectric layer. After this first dielectric layer is formed, the method forms a second (thicker) dielectric layer over the first dielectric layer. After this, the standard contacts are formed through the insulating layer to the source, drain, gate, etc. of the transistor. Additionally, reactive ion etching, chemical mechanical processing, and other back-end-of-line processing are performed. The back-end-of-line processes can introduce mobile ions into the dielectric over a transistor; however, the gettering agent traps the mobile ions and prevents the mobile ions from contaminating the transistor.

  • Patent number: 7544609
    Abstract: A method for integrating cap liner formation in back-end-of-line (BEOL) processing of a semiconductor device includes forming a trench structure within an insulating layer of the semiconductor device, depositing a first liner material over a top surface of the insulating layer, including sidewall and bottom surfaces of the trench, and partially filling the trench with a wiring metal material to a height corresponding to a final intended line height. A second liner material is over the wiring metal material, and a sacrificial fill material is formed over the second liner material. The sacrificial fill is planarized down to the level of the second liner material over the wiring metal material partially filling the trench, wherein a remaining portion of the second liner material defines a cap liner of the wiring metal.

  • Publication number: 20090117360
    Abstract: A non-photosensitive polymeric resist containing at least two immiscible polymeric block components is deposited on the planar surface. The non-photosensitive polymeric resist is annealed to allow phase separation of immiscible components and developed to remove at least one of the at least two polymeric block components. Nanoscale features, i.e., features of nanometer scale, including at least one recessed region having a nanoscale dimension is formed in the polymeric resist. The top surface of the polymeric resist is modified for enhanced etch resistance by an exposure to an energetic beam, which allows the top surface of the patterned polymeric resist to become more resistant to etching processes and chemistries. The enhanced ratio of etch resistance between the two types of surfaces provides improved image contrast and fidelity between areas having the top surface and the at least one recessed region.

  • Patent number: 7475368
    Abstract: A system, a method and a computer program product for analyzing a circuit design provide for discretizing the circuit design into a series of pixels. A fraction of at least one constituent material is determined for each pixel. A deflection is also determined for each pixel. The deflection is predicated upon a planarizing of the pixel, and it is calculated while utilizing an algorithm that includes the fraction of the at least one constituent material. A series of deflections for the series of pixels may be mapped and evaluated.

  • Patent number: 7456098
    Abstract: Stacked via pillars, such as metal via pillars, are provided at different and designated locations in IC chips to support the chip structure during processing and any related processing stresses such as thermal and mechanical stresses. These stacked via pillars connect and extend from a base substrate of the strip to a top oxide cap of the chip. The primary purpose of the stacked via pillars is to hold the chip structure together to accommodate any radial deformations and also to relieve any stress, thermal and/or mechanical, build-tip during processing or reliability testing. The stacked via pillars are generally not electrically connected to any active lines or vias, however in some embodiments the stacked via pillars can provide an additional function of providing an electrical connection in the chip.

  • Publication number: 20070273004
    Abstract: The invention forms integrated circuit devices of similar structure and dissimilar depth, such as interconnects and inductors, simultaneously. The invention deposits a conformal polymer over an area on a substrate with vias and an area without vias. Simultaneously, cavities are formed in the areas with and without vias. The depth of the cavities formed in the areas with vias will extend deeper into the substrate than the cavities formed in areas without vias. Such occurs because the polymer deposits unevenly along the surface of the substrate and more specifically, more thinly in areas with underlying depressions. Once filled with a conductive material, cavities which extend more deeply into the substrate, which were formed in areas with vias, become inductors, and the cavities which extend less deeply into the substrate, which were formed in areas without vias, become interconnects.

  • Patent number: 7253100
    Abstract: Methods are disclosed for reducing damage to an ultra-low dielectric constant (ULK) dielectric during removal of a planarizing layer such as a crosslinked polymer. The methods at least partially fill an opening with an at most lightly crosslinked polymer, followed by the planarizing layer. When the at most lightly crosslinked polymer and planarizing layer are removed, the at most lightly crosslinked polymer removal is easier than removal of the planarizing layer, i.e., crosslinked polymer, and does not damage the surrounding dielectric compared to removal chemistries used for the crosslinked polymer.
