Latest Patents

Michael A. Mitchell holds a patent for a "Bare die test and burn-in device." This device is designed to create temporary electrical connections between bonding pads on a die and external test connectors. The invention includes a die chuck, a fanout substrate, and a substrate chuck. The fanout substrate features conductive bumps that are strategically spaced for registration with the die bonding pads. In one embodiment, an alignment arrangement ensures precise registration between the die chuck and the substrate chuck. An alternative design incorporates a backside etched cavity in the fanout substrate, which exposes a transparent compliant material. This allows for visual observation of alignment while a lower frame facilitates lateral and angular positioning of the die chuck relative to the substrate chuck.
