发明名称 Wafer bonding material with embedded conductive particles
摘要 A material for bonding a first wafer to a second wafer, which includes an insulating adhesive with conductive particles embedded in the adhesive substance. When the adhesive is applied and melted or fused, and pressure is applied between the first wafer and the second wafer, the first wafer approaches the second wafer until a minimum separation is reached, defined by a dimension of the conductive particles. Each of the first wafer and the second wafer may have circuitry formed thereon, and the conductive particles may form a conductive path between the circuitry on one wafer and the circuitry on the other wafer. Advantageously, the high fusing temperature required by the insulating adhesive may also serve to activate a getter material, formed in the device cavity between the first wafer and the second wafer.
