Transient Liquid Phase Compositions Having Multi-Layer Particles

摘要

Transient liquid phase compositions and bonding assemblies are disclosed. In one embodiment, a transient liquid phase composition includes a plurality of particles. Each particle includes a core, an inner shell surrounding the core, the inner shell, and an outer shell surrounding the inner shell. The core is made of a first high melting temperature material, the inner shell is made of a second high melting temperature material, and the outer shell is made of a low melting temperature material. The melting temperature of the low melting temperature material is less than the melting temperature of both the first and second high melting temperature materials.
