Abstract:
1. A method comprising: providing a micro device wafer having micro devices supported by a wafer substrate, wherein each micro device includes a main portion and at least one contact point electrically and physically connected to and projecting from the main portion, and a multi-device lid substrate coupled to and spaced from the wafer substrate, the multi-device lid substrate having portions opposite each main portion and spaced from each opposite main portion by an empty gap; sawing through the multi-device lid substrate to a depth between the wafer substrate and the lid substrate, wherein the sawing forms an opening adjacent to at least one contact point of at least one device on an opposite side of the at least one contact point as the wafer substrate such that the at least one contact point is sandwiched between the wafer substrate and the opening; and forming a spacer between the wafer substrate and the lid substrate, wherein the formed spacer comprises a seal between the lid substrate and the wafer substrate and about each main portion between each main portion and each contact point and wherein the seal comprises a bond ring, wherein the multi-device lid substrate has a flat face opposite the wafer substrate extending across essentially an entirety of the wafer substrate, wherein the spacer includes a portion extending between the contact points and the lid substrate.
