摘要： A complementary metal oxide semiconductor (CMOS) circuit having integrated functional devices such as nanowires, carbon nanotubes, magnetic memory cells, phase change memory cells, ferroelectric memory cells or the like. The functional devices are integrated with the CMOS circuit. The functional devices are bonded (e.g. by direct bonding, anodic bonding, or diffusion bonding) to a top surface of the CMOS circuit. The functional devices are fabricated and processed on a carrier wafer, and an attachment layer (e.g. SiO2) is deposited over the functional devices. Then, the CMOS circuit and attachment layer are bonded. The carrier wafer is removed (e.g. by etching). The functional devices remain attached to the CMOS circuit via the attachment layer. Apertures are etched through the attachment layer to provide a path for electrical connections between the CMOS circuit and the functional devices.

摘要： A device structure provides improved efficiency of light emission from a light emitting element made of silicon while rendering such emission electrically controllable. Silicon in the light emitting element comprises fine microcrystals, which are miniaturized sufficiently to cause a quantum size effect. The microcrystals may be 10 nanometers (nm) or less in grain size. A dielectric film of 5 nm thick or less is formed containing therein such microcrystals. The microcrystal structure section is disposed between p- and n-type semiconductor layers. These layers are brought into electrical contact with the microcrystal structure only, while causing the remaining portions to be electrically insulative by a dielectric film or the like. Elementary particles of the opposite polarities, e.g. electrons and holes, are injected by tunnel effect into the microcrystals resulting in emission of light rays with increased efficiency.
