    Abstract: A process for making a DRAM-type cell includes growing layers of silicon germanium and layers of silicon, by epitaxy from a silicon substrate; superposing a first layer of Nnull doped silicon and a second layer of P doped silicon; and forming a transistor on the silicon substrate. The method also includes etching a trench in the extension of the transistor to provide an access to the silicon germanium layers relative to the silicon layers over a pre-set depth to form lateral cavities, and forming a capacitor in the trench and in the lateral cavities.

    Abstract: An electronic device, such as an opto-electronic device and an integrated semiconductor memory device, includes at least one integrated memory point structure including a quantum well semiconductor area buried in the substrate of the structure and disposed under the insulated gate of a transistor. A biasing voltage source is adapted to bias the structure to enable charging or discharging of charges in the quantum well or outside the quantum well.

    Abstract: A semiconductor device is provided that includes a semiconductor channel region extending above a semiconductor substrate in a longitudinal direction between a semiconductor source region and a semiconductor drain region, and a gate region extending in the transverse direction, coating the channel region, and insulated from the channel region. The source, channel, and drain regions are formed in a continuous semiconductor layer that is approximately plane and parallel to the upper surface of the substrate. Additionally, the source, drain, and gate regions are coated in an insulating coating so as to provide electrical insulation between the gate region and the source and drain regions, and between the substrate and the source, drain, gate, and channel regions. Also provided is an integrated circuit that includes such a semiconductor device, and a method for manufacturing such a semiconductor device.
