Abstract
Backside contacts wrapping around source/drain regions provide increased contact areas for electrical connections between field-effect transistors and metallization layers. Cavities formed within a device layer expose sidewalls of selected source/drain regions. The backside contacts extend within such cavities and adjoin the sidewall surfaces and bottom surfaces of the selected source/drain regions.
