Stacked microfeature devices and associated methods of manufacture are disclosed. A package in accordance with one embodiment includes first and second microfeature devices having corresponding first and second bond pad surfaces that face toward each other. First bond pads can be positioned at least proximate to the first bond pad surface and second bond pads can be positioned at least proximate to the second bond pad surface. A package connection site can provide electrical communication between the first microfeature device and components external to the package. A wirebond can be coupled between at least one of the first bond pads and the package connection site, and an electrically conductive link can be coupled between the first microfeature device and at least one of the second bond pads of the second microfeature device. Accordingly, the first microfeature device can form a portion of an electrical link to the second microfeature device.

A method for bonding a hermetic module to an electrode array including the steps of: providing the electrode array having a flexible substrate with a top surface and a bottom surface and including a plurality of pads in the top surface of the substrate; attaching the hermetic module to the bottom surface of the electrode array, the hermetic module having a plurality of bond-pads wherein each bond-pad is adjacent to the bottom surface of the electrode array and aligns with a respective pad; drill holes through each pad to the corresponding bond-pad; filling each hole with biocompatible conductive ink; forming a rivet on the biocompatible conductive ink over each pad; and overmolding the electrode array with a moisture barrier material.
