Abstract
A semiconductor structure includes a source/drain (S/D) region, one or more dielectric layers over the S/D region, one or more semiconductor channel layers connected to the S/D region, an isolation structure under the S/D region and the one or more semiconductor channel layers, and a via under the S/D region and electrically connected to the S/D region. A lower portion of the via is surrounded by the isolation structure and an upper portion of the via extends vertically between the S/D region and the isolation structure.
