  • Publication number: 20250098187
    Abstract: A memory cell structure includes a transistor structure and a capacitor structure, where the capacitor structure includes a hydrogen absorption layer. The hydrogen absorption layer absorbs hydrogen, which prevents or reduces the likelihood of the hydrogen diffusing into an underlying metal-oxide channel of the transistor structure. In this way, the hydrogen absorption layer minimizes and/or reduces the likelihood of hydrogen contamination in the metal-oxide channel, which may enable a low current leakage to be achieved for the memory cell structure and reduces the likelihood of data corruption and/or failure of the memory cell structure, among other examples.
