Patent ID: 7504331

Claim:
A method of forming an electrical interconnection structure for connecting two circuit elements comprising: forming a first circuit; forming a contact pad electrically connected to the first circuit, the contact pad including an outer layer of first reactive molecules; and, exposing the first contact pad to freely moving particles, the surface of the freely moving particles including a corresponding outer layer of a second reactive molecules wherein one of the first reactive molecules and the second reactive molecules is an acetylene functional group and wherein one of the first reactive molecules and the second reactive molecules is an azide group such that when the first reactive molecules and the second reactive molecules come into contact in the presence of a copper catalyst, the first reactive molecule and the second reactive molecule form a triazole linker molecule via a dipolar addition reaction, the triazole linker molecule that bonds the freely moving particle to the contact pad, after bonding the particle to the contact pad, a portion of the particle surface to create an uneven surface including a contact asperity, the contact asperity including a point that rises higher above the contact pad than any other points on a surface of an area immediately surrounding the contact asperity.
