Abstract:
1. A method for fabricating a micro-electromechanical system, the method comprising: providing a first micromachined apparatus having a front side including at least one micromachined structure and raised offset structures built upon the front side; providing a second micromachined apparatus having a front side including at least one micromachined structure; and bonding the front side of the first micromachined apparatus and the front side of the second micromachined apparatus together, wherein one micromachined apparatus comprises a micro-electromechanical system wafer having micromachined mechanical and electrical components and the other micromachined apparatus comprises an integrated circuit wafer having micromachined integrated circuitry, and wherein the raised offset structures separate the micromachined structures of the first and second apparatuses by a predetermined distance, and wherein bonding the front side of the first micromachined apparatus and the front side of the second micromachined apparatus together comprises solder bump and gold compression between bond pads on the raised offset structures and the front side of the second micromachined apparatus.
