Title:
SEMICONDUCTOR BRIDGE, IGNITER, AND GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2007/029682
Kind Code:
A1
Abstract:
A semiconductor bridge, an igniter, and gas generator for satisfying a high-speed responsiveness required by a side inflator or the like. The semiconductor bridge comprises a bridge circuit generating heat by being energized and provided on a substrate (10), wherein the bridge circuit has an insulating first layer (24) formed on the substrate (10), and an ignition bridge as a second layer (22) provided at the upper layer of the first layer (24), the width of the bridge circuit of the first layer (24) is almost equal to the width of the bridge circuit of the second layer (22), and spaces provided around the bridge circuits can minimize the diffusions of current and heat to the substrate (10) to thereby provide ignition characteristics quick in igniting time. The igniter and the gas generator are provided with the above semiconductor bridge.
