  • Publication number: 20240136226
    Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.

  • Patent number: 11640971
    Abstract: A deep trench is formed in a substrate, and a layer stack including at least three metallic electrode plates interlaced with at least two node dielectric layers is formed in, and over, the deep trench. A contact-level dielectric material layer over the layer stack, and contact via cavities are formed therethrough. The depths of the contact via cavities are differentiated by selectively increasing the depth of a respective subset of the contact via cavities by performing at least twice a combination of processing steps that includes an etch mask formation process and an etch process. A combination of a dielectric contact via liner and a plate contact via structure can be formed within each of the contact via cavities. Plate contact via structures that extend through any metallic electrode plate can be electrically isolated from such a metallic electrode plate by a respective dielectric contact via liner.
