摘要:
A semiconductor device includes a substrate. On at least one face of that substrate, integrated circuits are formed. At least one electromagnetic waveguide is also included, that waveguide including two metal plates that are placed on either side of at least one part of the thickness of the substrate and are located facing each other. Two longitudinal walls are placed facing each other and are formed by metal vias made in holes passing through the substrate in its thickness direction. The metal vias electrically connect the two metal plates.

An electronic device includes a semiconductor component having a support substrate in the form of a wafer. On one side of this substrate integrated circuits including an RF circuit and an antenna connected to this RF circuit are formed. A metal layer is situated on the other side of the substrate, facing the antenna. At least on metal via is provided in a through-hole in the substrate, this via being connected at one end to the metal layer and at the other end to the RF circuit, at the same reference potential node as the antenna.
摘要:
An antenna is formed with a self-supporting structure (1), a dielectric structure (2), and a conducting structure (3), each structure being formed from at least one structural element (10; 21, 22; 31-34). The structural elements of the different structures (1, 2, 3) constitute a stack in which these elements (10; 21, 22; 31-34) are connected to each other, and the dielectric structure (2) is formed in the stack by nano-imprinting.

A multilayer semiconductor device includes at least one structure for transmitting electrical signals, and in particular, microwave signals. The device includes at least one electrically conductive enclosure that includes a bottom plate and a top plate in two different layers. Lateral walls connect the bottom and top plates. Electrically conductive connecting strips extend into the enclosure and are in an intermediate layer, and are electrically insulated from the enclosure. The enclosure has at least one passage through which extends electrical connections of the connecting strips, which are also electrically insulated from the enclosure.

A stand-alone device comprising a silicon wafer having its front surface including a first layer of a first conductivity type and a second layer of a second conductivity type forming a photovoltaic cell; first vias crossing the wafer from the rear surface of the first layer and second vias crossing the wafer from the rear surface of the second layer; metallization levels on the rear surface of the wafer, the external level of these metallization levels defining contact pads; an antenna formed in one of the metallization levels; and one or several chips assembled on said pads; the metallization levels being shaped to provide selected interconnects between the different elements of the device.
摘要:
A semiconductor device includes a substrate, for example made of silicon, and layers, deposited on this substrate. Within at least one of these layers a radio signal transmission/reception antenna is formed. Located between the antenna and the substrate, a screen for collecting induced currents between this antenna and this substrate is formed within at least one of the layers. The screen includes at least one main branch connected to a fixed potential, for example a ground reference, and a plurality of secondary branches connected to the main branch at one of their extremities. The collector screen accordingly presents a tree-like structure.

A variable impedance device includes a passive tuner that includes at least one variable component, which is controllable to apply a variable impedance value to an input signal of the passive tuner. A low noise amplifier is configured to supply the input signal to the passive tuner by amplifying an input RF (radio frequency) signal.
