  • Publication number: 20210265369
    Abstract: Embodiments provide raised pad formations for step contacts in three-dimensional structures formed on microelectronic workpieces. Steps are formed in a multilayer stack that is used for the three-dimensional structure. The multilayer stack includes alternating non-conductive and conductive layers. For one embodiment, alternating oxide and polysilicon layers are used. The steps expose contact regions on different conductive layers. Material layers are formed on the contact regions to form raised pads. The material layers preferably have a high selectivity with respect to the non-conductive material for etch processes. A protective layer is formed over the steps and the raised pads, and contact holes are formed through the protective layer to the raised pads. Contacts are then formed within the contact holes. The raised pads inhibit punch-through of the non-conductive layers during the forming of the contact holes thereby improving performance of resulting devices formed in the microelectronic workpieces.

  • Publication number: 20200273992
    Abstract: Residue at the base of a feature in a substrate to be etched is limited so that improved profiles may be obtained when forming vertical, narrow pitch, high aspect ratio features, for example fin field effect transistor (FinFET) gates. A thin bottom layer of the feature is formed of a different material than the main layer of the feature. The bottom material may be comprised of a material that preferentially etches and/or preferentially oxidizes as compared to the main layer. The bottom layer may comprise silicon germanium. The preferential etching characteristics may provide a process in which un-etched residuals do not remain. Even if residuals remain, after etch of the feature, an oxidation process may be performed. Enhanced oxidation rates of the bottom material allow any remaining residual to be oxidized. Plasma oxidation may be used. The oxidized material may then be removed by utilizing standard oxide removal mechanisms.

  • Patent number: 9040448
    Abstract: The present invention relates to a method of preparing a spherical mesoporous silica structure containing silver nanoparticles dispersed therein by adding a silver nitrate solution to an aqueous surfactant solution and performing a sol-gel process and to spherical mesoporous silica prepared thereby. The spherical mesoporous silica is cost-effective compared to a conventional method that uses silver nanoparticles as a raw material, because the silver nitrate solution that is inexpensive compared to silver nanoparticles is used. Also, the spherical mesoporous silica can be with high productivity in large amounts, and thus is easily commercialized. Moreover, because silver nanoparticles are incorporated into the pores of the mesoporous silica, the silver nanoparticles are used stably and do not change color and odor. In addition, the spherical mesoporous silica exhibits various additional effects, including far-infrared ray emission and deodorization, attributable to silica.

  • Patent number: 8835328
    Abstract: Methods for fabricating integrated circuits are provided herein. In an embodiment, a method for fabricating an integrated circuit includes providing a mandrel layer overlying a semiconductor substrate and patterning the mandrel layer into mandrel structures. The method further includes forming a protective layer between the mandrel structures. Spacers are formed around each of the mandrel structures and overlying the protective layer to define exposed regions of the protective layer and covered regions of the protective layer. The exposed regions of the protective layer are etched using the spacers and the mandrel structures as a mask. The spacers are removed from the covered regions of the protective layer. The covered regions of the protective layer form mask segments for etching the semiconductor substrate. The method removes the mandrel structures and etches the semiconductor substrate exposed between mask segments to form semiconductor fin structures.
