Abstract:
1. An interconnect system comprising: a circuit coupled to a contact pad; a first particle bonded to the contact pad, exposing the first particle bonded to the contact pad to a plurality of second particles, the first particle and the second particles being substantially spherical, the first particle being larger in size than the second particles and the second particles having a diameter between 1 and 10 micrometers such that the second particles attach to a surface of the first particle wherein a bond between the contact pad and the first particle is a covalent bond and a bond between the first particle and the second particles is also a covalent bond; and, a conformal metal coating covering the contact pad the first particle and the second particles, the conformal metal coating deposited after the particle has bonded first to the contact pad, and the second particles attach to the first particle thereby creating a metal layer that conforms to the contours of a surface of the combined contact pad, first particle bonded to the contact pad and second particles attached to the first particle.
