Abstract:
1. A method comprising: providing a first substrate having a first surface and a second surface opposite the first surface; mounting first device and second device on the first surface, the second device adjacent the first device; forming first internal interconnects and second internal interconnects on the first surface, the first internal interconnects between the first device and the second internal interconnects and the second internal interconnects between the second device and the first internal interconnects; configuring a removable region between the first device and the second device, the removable region extending from the first surface to the second surface of the first substrate, the removable region having a region length longer than a region width; providing a second substrate over the first substrate, the second substrate having a third surface and a fourth surface opposite the third surface such that the third surface faces the first surface; forming an aperture between the first device and the second device, the aperture extending from the third surface to the fourth surface of the second substrate, the aperture in vertical alignment with the removable region, the aperture having an aperture width smaller than the region width of the removable region; and wherein the aperture is configured to facilitate outflow of materials from cavities between the first substrate and the second substrate.
