Patent ID: 6938334

Claim:
A method for fabrication of microelectromechanical systems (MEMS) integrated micro devices, the method comprising: micromachining an array of first three-dimensional micromechanical device features in a first silicon wafer including micromachining an array of both partial and complete stand-alone three-dimensional micromechanical device features; micromachining an array of second three-dimensional micromechanical device features in a second silicon wafer, the second three-dimensional micromechanical device features being configured to cooperate with the first three-dimensional micromechanical device features when joined therewith, and including micromachining an array of both partial and complete stand-alone three-dimensional micromechanical device features, the partial device features in the second silicon wafer being configured to be joined with the partial device features in the first silicon wafer; mutually aligning the first and second arrays of device features; permanently joining the first and second arrays of device features into an array of integrated micro devices as a function of permanently joining the first and second silicon wafers into a single composite wafer; and subsequently separating the array of integrated devices into individual devices each having a set of the first and second device features.
