  • Patent number: 8519892
    Abstract: A semiconductor chip integrating a transceiver, an antenna, and a receiver is provided. The transceiver is located on a front side of a semiconductor substrate. A through substrate via provides electrical connection between the transceiver and the receiver located on a backside of the semiconductor substrate. The antenna connected to the transceiver is located in a dielectric layer located on the front side of the substrate. The separation between the reflector plate and the antenna is about the quarter wavelength of millimeter waves, which enhances radiation efficiency of the antenna. An array of through substrate dielectric vias may be employed to reduce the effective dielectric constant of the material between the antenna and the reflector plate, thereby reducing the wavelength of the millimeter wave and enhance the radiation efficiency. A design structure for designing, manufacturing, or testing a design for such a semiconductor chip is also provided.

  • Patent number: 8497203
    Abstract: Semiconductor structures with airgaps and/or metal linings and methods of manufacture are provided. The method of forming an airgap in a wiring level includes forming adjacent wires in a dielectric layer.

The method further includes removing exposed portions of the first layer and the dielectric layer to form trenches between the adjacent wires. The method further includes forming an interlevel dielectric layer upon the dielectric layer, where the interlevel dielectric layer is pinched off from filling the trenches so that an airgap is formed between the adjacent wires. A metal liner can also be formed in the trenches, prior to the formation of the airgap.
