Abstract:
One or more embodiments provide for a composition that includes (i) organic material that is conductive or semi-conductive, and (ii) conductor and/or semiconductor particles other than the organic material. The organic material and the conductor and/or semiconductor particles are combined to provide the composition with a characteristic of being (i) dielectric in absence of a voltage that exceeds a characteristic voltage level, and (ii) conductive with application of the voltage exceeding the characteristic voltage level.
Abstract:
Various aspects provide for structures and devices to protect against spurious electrical events (e.g., electrostatic discharge). Some embodiments incorporate a voltage switchable dielectric material (VSDM) bridging a gap between two conductive pads. Normally insulating, the VSDM may conduct current from one pad to the other during a spurious electrical event (e.g,. shunting current to ground). Some aspects include gaps having a gap width that is greater than 50% of a spacing between electrical leads connected to the pads. Some devices include single layers of VSDM. Some devices include multiple layers of VSDM. Various devices may be designed to increase a ratio of active volume (of VSDM) to inactive volume.
Abstract:
A substrate device includes a layer of non-linear resistive transient protective material and a plurality of conductive elements that form part of a conductive layer. The conductive elements include a pair of electrodes that are spaced by a gap, but which electrically interconnect when the transient protective material is conductive. The substrate includes features to linearize a transient electrical path that is formed across the gap.
Abstract:
A core layer structure is provided for substrate and packed devices. The core layer structure includes a first layer, a second layer combined with the first layer. A layer of voltage switchable dielectric (VSD) material provided in between the first layer and second layer.
