  • Publication number: 20220246626
    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.
