Abstract: Apparatuses including spark gap structures for electrical overstress (EOS) monitoring or protection, and associated methods, are disclosed. In an aspect, a spark gap device includes first and second conductive layers formed over a substrate, where the first and second conductive layers are electrically connected to first and second voltage nodes, respectively. The first conductive layer includes a plurality of arcing tips configured to form arcing electrode pairs with the second conductive layer to form an arc discharge in response to an EOS voltage between the first and second voltage nodes. The spark gap device further includes a series ballast resistor electrically connected between the arcing tips and the first voltage node, where the ballast resistor in formed in a metallization layer over the substrate and a resistance of the series ballast resistor is substantially higher than a resistance of the second conductive layer.

Abstract: Apparatuses including spark gap structures for electrical overstress (EOS) monitoring or protection, and associated methods, are disclosed. In an aspect, a vertical spark gap device includes a substrate having a horizontal main surface and a plurality of pairs of conductive layers over the horizontal main surface. Different ones of the pairs are separated by different vertical distances such that each pair serves as an arcing electrode pair and different ones of the arcing electrode pairs are configured to arc discharge at different voltages.

Abstract: Apparatuses including spark gap structures for electrical overstress (EOS) monitoring or protection, and associated methods, are disclosed. In an aspect, a vertical spark gap device includes a substrate having a horizontal main surface, a first conductive layer and a second conductive layer each extending over the substrate and substantially parallel to the horizontal main surface while being separated in a vertical direction crossing the horizontal main surface. One of the first and second conductive layers is electrically connected to a first voltage node and the other of the first and second conductive layers is electrically connected to a second voltage node. The first and second conductive layers serve as one or more arcing electrode pairs and have overlapping portions configured to generate one or more arc discharges extending generally in the vertical direction in response to an EOS voltage signal received between the first and second voltage nodes.

Abstract: The disclosed technology generally relates to electrical overstress protection devices, and more particularly to electrical overstress monitoring devices for detecting electrical overstress events in semiconductor devices. In one aspect, a device configured to monitor electrical overstress (EOS) events includes a pair of spaced conductive structures configured to electrically arc in response to an EOS event, wherein the spaced conductive structures are formed of a material and have a shape such that arcing causes a detectable change in shape of the spaced conductive structures, and wherein the device is configured such that the change in shape of the spaced conductive structures is detectable to serve as an EOS monitor.
