Abstract
This invention relates to a solid-state or integrated circuit-type igniter die (10) having a bridge (18) that is formed on a non-planar surface of a substrate (12), and which therefore has a non-planar configuration. Igniter die (10), according to this invention therefore has a three-dimensional configuration and, preferably, a configuration that can enclose a reactive material (26) therein. In a typical embodiment, the bridge (18) of an igniter element of this invention has a tubular configuration. Reactive material (26) is disposed within the interior of the tube (14) and a charge of electric current is flowed through the tube (14) from o the other to form a plasma that initiates the remaining reactive material (26).
