摘要:
An apparatus and method for detecting characteristics of a microelectronic substrate. The microelectronic substrate can have a first surface with first topographical features, such as roughness elements, and a second surface facing opposite from the first surface and having second topographical features, such as protruding conductive structures. In one embodiment, the apparatus can include a support member configured to carry the microelectronic substrate with a first portion of the first surface exposed and a second portion of the second surface exposed. The apparatus can further include a topographical feature detector positioned proximate to support member and aligned with the first portion of the first surface of the microelectronic substrate to detect characteristics, such as a roughness, of the first surface while the microelectronic substrate is carried by the support member.

摘要:
Semiconductor devices and stacked die assemblies, and methods of fabrication are provided. In various embodiments, the die assembly comprises a first die mounted on a substrate and a second die mounted on the first die. In one embodiment, the second die has a recessed edge along the perimeter of the bottom surface to provide clearance for a bonding element extending from bond pads on the first die to pads on the substrate, thus eliminating the need for a spacer between the two dies. In another embodiment, the second die is at least partially disposed within a recess in the upper surface of the first die. In another embodiment, an adhesive element is disposed within a recess in the bottom surface of the first die for attaching the first die to the substrate. In yet another embodiment, the first die is at least partially disposed within a recess within the bottom surface of the second die. The stacked die assemblies can be encapsulated to form semiconductor packages.
