Abstract
A flat field transistor (FFT) based dynamic random-access memory (DRAM) (FFT-DRAM) is disclosed. The FFT-DRAM comprises an epitaxially grown source region comprising a source extension and an epitaxial source over and in contact with the source extension. The epitaxially grown source region is over a surface of a semiconductor substrate. The FFT-DRAM further comprises a trench capacitor structurally integrated into the epitaxially grown source region. The trench capacitor has a first terminal formed by the epitaxially grown source region and a second terminal being a conductive material filling one or more trenches of the trench capacitor. The second terminal is connected to a ground terminal or a fixed voltage terminal.
