Abstract
Attaching a semiconductor chip to a substrate by applying mechanical vibrations () to a polymeric compound () and the contacting areas () of a first () and a second () metallic member immersed in the compound, while the two metallic members approach () each other until they touch. The mechanical vibration causes displacements of the first member relative to the second member, and the vibration includes displacements () oriented at right angles to the direction () of the approach. The polymeric compound () includes a non-conductive adhesive resin paste (NCP) and filler particles; the paste is deposited before the attaching step. The first member () is affixed to the chip and the second member () to the substrate.
