Patent ID: 8020489

Claim:
A squib including: (a) a cup body and a header for holding a plurality of electrode pins insulated from one another and closing the opening of said cup body; (b) ignition powder and a semiconductor bridge (SCB) chip in said cup body connected to said electrode pins for igniting said ignition powder by externally applying electric current; (c) said SCB chip comprising: (i) a substrate and a thin film resistor formed on an upper surface of said substrate, (ii) a capacitor electrically connected to said electrode pins in parallel with the thin film resistor of said SCB chip, (iii) an SCB top electrode on a top surface of said SCB, an SCB side electrode on a side surface of said SCB, and optionally an SCB bottom electrode on a bottom surface of said SCB; (d) said capacitor being arranged above said header, and having capacitor electrodes at opposite ends of the capacitor; (e) said SCB chip being (i) directly mounted on said capacitor so that the capacitor electrodes at opposite ends of the capacitor contact SCB electrodes; and (ii) smaller than the capacitor; and (f) the top, side and optional bottom SCB electrodes and the capacitor electrodes being electrically connected with each other by solder or conductive paste, whereby (i) the SCB chip is electrically connected with the capacitor electrodes; and (ii) the thin film resistor of the SCB chip and the capacitor are in parallel electrical connection with said plurality of electrode pins without electrical connection to the substrate.
