摘要： An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, εr that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.

摘要： A method of forming a multi-chip system is disclosed. The method includes forming one or more bumps on respective conductive contact pads of a first electronic device, forming one or more mini-bumps on respective conductive contact pads of a second electronic device, and aligning respective one or more mini-bumps with respective one or more bumps. The method further includes performing a bump bonding process that exerts compression force on one or both the first electronic device and the second electronic device to compress the one or more mini-bumps into the one or more bumps to form one or more bump bond structures that bond the second electronic device to the first electronic device.

摘要： Test structures and methods for superconducting bump bond electrical characterization are used to verify the superconductivity of bump bonds that electrically connect two superconducting integrated circuit chips fabricated using a flip-chip process, and can also ascertain the self-inductance of bump bond(s) between chips. The structures and methods leverage a behavioral property of superconducting DC SQUIDs to modulate a critical current upon injection of magnetic flux in the SQUID loop, which behavior is not present when the SQUID is not superconducting, by including bump bond(s) within the loop, which loop is split among chips. The sensitivity of the bump bond superconductivity verification is therefore effectively perfect, independent of any multi-milliohm noise floor that may exist in measurement equipment.

摘要： An electrical connection device is provided that includes a first electrical connector having first electrical contacts formed therein and a second electrical connector having second electrical contacts formed therein. A flexible silicon connector section connects the first electrical connector and the second electrical connector. The connector section includes flexible strands separated by slots, where the flexible strands are flexible in directions orthogonal to a longitudinal direction of the connector section. The flexible strands include metal traces deposited therein to provide an electrical connection between the first electrical connector and the second electrical connector.

摘要： A flexible connector includes a unitary connector block having first and second board-facing areas. The first and second board-facing areas are longitudinally spaced from each other on a chosen surface of the connector block. The connector block includes a block body transversely separating the chosen surface from an opposing surface oppositely facing from the chosen surface. The connector block includes a flexible connector bridge longitudinally interposed between the first and second board-facing areas. A first connector port is located within the first board-facing area. A second connector port is located within the second board-facing area. A connector trace extends through at least a portion of the block body between the first and second board-facing areas. The connector trace electrically connects the first and second connector ports. Methods of making and using the flexible connector are also included.
