A cellular communication system comprises a network supporting user equipment over an air interface, the network having a hierarchical cell arrangement with overlay cells and underlay cells. An underlay base station is associated with a subset of registered user equipment. An activation server switches the underlay base station between an inactive mode and an active mode in response to detecting that registered user equipment meets a location criterion. The underlay base station only supports user equipment when in the active mode, e.g., it may only transmit a pilot signal in this mode. Interference and power consumption may be substantially reduced by sending the base station into the inactive mode thereby resulting in increased capacity of the cellular communication system as a whole.

The formation of a gap-filling silicon oxide layer with reduced volume fraction of voids is described. The deposition involves the formation of an oxygen-rich less-flowable liner layer before an oxygen-poor more-flowable gapfill layer. However, the liner layer is deposited within the same chamber as the gapfill layer. The liner layer and the gapfill layer may both be formed by combining a radical component with an unexcited silicon-containing precursor (i.e. not directly excited by application of plasma power). The liner layer has more oxygen content than the gapfill layer and deposits more conformally. The deposition rate of the gapfill layer may be increased by the presence of the liner layer. The gapfill layer may contain silicon, oxygen and nitrogen and be converted at elevated temperature to contain more oxygen and less nitrogen. The presence of the gapfill liner provides a source of oxygen underneath the gapfill layer to augment the gas phase oxygen introduced during the conversion.

A substrate integrated waveguide (SIW) slot full-array antenna fabricated employing printed circuit board technology. The SIW slot full-array antenna using either single or multi-layer structures greatly reduces the overall height and physical steering requirements of a mobile antenna when compared to a conventional metallic waveguide slot array antenna. The SIW slot full-array antenna is fabricated using a low-loss dielectric substrate with top and bottom metal plating. An array of radiating cross-slots is etched in to the top plating to produce circular polarization at a selected tilt-angle. Lines of spaced-apart, metal-lined vias form the sidewalls of the waveguides and feeding network. In multi-layer structures, the adjoining layers are coupled by transverse slots at the interface of the two layers.

Some embodiments provide a novel way to insert a service (e.g., a third party service) in the path of a data message flow, between two machines (e.g., two VMs, two containers, etc.) in a public cloud environment. For a particular tenant of the public cloud, some embodiments create an overlay logical network with a logical overlay address space. To perform a service on data messages of a flow between two machines, the logical overlay network passes to the public cloud's underlay network the data messages with their destination address (e.g., destination IP addresses) defined in the logical overlay network. The underlay network (e.g., an underlay default downlink gateway) is configured to pass data messages with such destination addresses (e.g., with logical overlay destination addresses) to a set of one or more service machines. The underlay network (e.g., an underlay default uplink gateway) is also configured to pass to the particular tenant's public cloud gateway the processed data messages that are received from the service machine set and that are addressed to logical overlay destination addresses. The tenant's public cloud gateway is configured to forward such data messages to a logical forwarding element of the logical network, which then handles the forwarding of the data messages to the correct destination machine.

A wafer scale semiconductor integrated circuit packaging technique provides a hermetic seal for the individual integrated circuit die formed as part of the wafer scale structure. A semiconductor wafer is manufactured to include a number of individual semiconductor die. Each individual die formed on the wafer includes a number of bond pads that are exposed on the die surface in various locations to provide electrical connections to the circuitry created on the die. The wafer further includes a planar glass sheet that is substantially the same size as the wafer, the glass sheet being adhered to the wafer using a suitable adhesive. The glass sheet has a number of pre-formed holes in it, the arrangement of the pre-formed holes corresponding to the location of the bond pads at each of the individual semiconductor die formed as part of the wafer structure. Following adherence of the glass sheet to the semiconductor wafer utilizing the intermediate adhesive material, metal connections are made between pads formed on the glass sheet and the bond pads formed on the integrated circuit die. Solder balls are then attached to the pads on the glass sheet to provide a conductive flow between the solder balls and the bond pads. After the solder balls are attached, trenches are cut around each of the individual die on the wafer. The trenches are cut at an angle and extend through the glass sheet and the intermediate adhesive material and into the semiconductor substrate in which the integrated circuits are formed. After the trenches are cut around each individual semiconductor die, a noble metal is deposited on the sidewalls of the trench to extend over the interface between the glass sheet, the adhesive material and the semiconductor die. The wafer is then cut along the noble metal lined trenches to provide individual, hermetically sealed packaged integrated circuit die.

A layer of nanopaiticles having a dimension on the order of 10 nm is employed to form a current constricting layer or as a hardmask for forming a current constricting layer from an underlying insulator layer. The nanoparticles are preferably self-aligning and / or self-planarizing on the underlying surface. The current constricting layer may be formed within a bottom conductive plate, within a phase change material layer, within a top conductive plate, or within a tapered liner between a tapered via sidewall and a via plug contains either a phase change material or a top conductive material. The current density of the local structure around the current constricting layer is higher than the surrounding area, thus allowing local temperature to rise higher than surrounding material. The total current required to program the phase change memory device, and consequently the size of a programming transistor, is reduced due to the current constricting layer.
