    摘要: A method of forming contacts for semiconductor devices, the method including depositing an inter-level dielectric (ILD) over a plurality of gate stacks, in which the divots within the inter-level dielectric layer are defined by the spaces between the gate stacks, filling the divots with an initial fill material, depositing a masking material on the dielectric over the gate stacks, and selectively etching the fill material to form contact vias. The fill material may be a self-assembly material such as a multi-block copolymer in which the blocks self organize vertically within the divots, so that a selective etch of the block material will remove the vertically organized blocks from the divot, but leave at least one block over the gate regions. In another embodiment, the fill material may be a metal, and the masking material may be a parylene based polymer.

    摘要: Devices and methods are presented to fabricate diffusion barrier layers on a substrate. Presently, barrier layers comprising a nitride layer and a pure metal layer are formed using a physical vapor deposition (PVD) process that requires multiple ignition steps, and results in nitride-layer thicknesses of no less than 2 nm. This invention discloses devices and process to produce nitride-layers of less than

    摘要: A semiconductor device, such as an inductor, is formed with an air gap. A first level has an intra-metal dielectric layer including one or more inductor loops, one or more vias, and one or more copper bulkhead structures. An inter-level dielectric layer is formed over the first level. An extraction via is formed through the intra-metal dielectric layer and inter-level dielectric layer. An air gap is formed between inductor loops by removing portions of the intra-metal dielectric layer coupled to the extraction via using a supercritical fluid process, and forming a non-conformal layer to seal the extraction via. The air gap may be filled with an inert gas, like argon or nitrogen.

    摘要: A microelectronic structure and a method for fabricating the microelectronic structure use a dielectric layer that is located and formed upon a first conductor layer. An aperture is located through the dielectric layer. The aperture penetrates vertically into the first conductor layer and extends laterally within the first conductor layer beneath the dielectric layer while not reaching the dielectric layer, to form an extended and winged aperture. A contiguous via and interconnect may be formed anchored into the extended and winged aperture while using a plating method, absent voids
