  • Publication number: 20210312975
    Abstract: A memory device is disclosed, in which node contacts extend into a substrate, where they are come into electrical connection with active areas. This allows greater contact areas between the node contacts and the active areas and electrical connection of the node contacts with high ion concentration portions of the active areas. As a result, even when voids are formed in the node contacts, the node contacts can still possess desired connection performance. For node contacts allowed to contain voids, this enables them to be fabricated faster with lower difficulty, thus increasing manufacturing throughput of the memory device.
