Latest Patents

Margetts' latest patents focus on methods of bonding electronic devices to ceramic substrates. One notable invention is a silver metallizing paste designed for the attachment of silicon semi-conductive devices in lead-frame packages, specifically ceramic packages. This innovative paste is less expensive than traditional gold preforms while providing superior electrical and thermal conductivity, as well as higher bond strength compared to silver polyimides. The formulation consists of 25 to 95% silver blended with a low-melting glass, preferably containing 95-96% PbO, and is created with a suitable vehicle at 75-85% solids. This paste is particularly beneficial in MOS technology, where low contact resistance is essential, and it serves as a solder substitute for bonding chip capacitors. Additionally, it is advantageous for attaching larger-area integrated circuits, as it avoids the stress cracking associated with gold-silicon eutectic bonding.
