    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: An exemplary method lines the sidewalls of a first opening with a sacrificial material and then fills the first opening with a metallic conductor in a manner such that the metallic conductor contacts the substrate. Next, the method selectively removes the sacrificial material, to create at least one “second” opening along the metallic conductor within the first opening. The method selectively removes portions of the first insulator layer through the second opening to leave at least one air gap between the metallic conductor and the first insulator layer in the lower region of the second opening.

    摘要: A semiconductor substrate having an isolation region and method of forming the same. The method includes the steps of providing a substrate having a substrate layer, a buried oxide (BOX), a silicon on insulator (SOI) layer, a pad oxide layer, and a pad nitride layer, forming a shallow trench region, etching the pad oxide layer to form ears and etching the BOX layer to form undercuts, depositing a liner on the shallow trench region, depositing a soft mask over the surface of the shallow trench region, filling the shallow trench region, etching the soft mask so that it is recessed to the top of the BOX layer, etching the liner off certain regions, removing the soft mask, and filling and polishing the shallow trench region. The liner prevents shorting of the semiconductor device when the contacts are misaligned.
