  • Patent number: 11854868
    Abstract: Small sized and closely pitched features can be formed by patterning a layer to have holes therein and then expanding the layer so that the holes shrink. If the expansion is sufficient to pinch off the respective holes, multiple holes can be formed from one larger hole. Holes smaller and of closer pitch than practical or possible may be obtained in this way. One process for expanding the layer includes implanting a dopant species having a larger average atomic spacing than does the material of the layer.

  • Patent number: 11855097
    Abstract: A semiconductor device includes a gate stack, an epitaxy structure, a first spacer, a second spacer, and a dielectric residue. The gate stack is over a substrate. The epitaxy structure is formed raised above the substrate. The first spacer is on a sidewall of the gate stack. The first spacer and the epitaxy structure define a void therebetween. The second spacer seals the void between the first spacer and the epitaxy structure. The dielectric residue is in the void and has an upper portion and a lower portion under the upper portion. The upper portion of the dielectric residue has a silicon-to-nitrogen atomic ratio higher than a silicon-to-nitrogen atomic ratio of the lower portion of the dielectric residue.
