An integrated circuit die having an active area that must remain exposed after packaging is secured by a compliant die attachment by which the integrated circuit die is held in position within a transfer mold during encapsulation. The compliant die attachment may comprise a flexible, compressible tape having pressure-sensitive adhesive, alone or with a rigid substrate support, or a compliant adhesive preferably applied only around a periphery of the die attach area. Deformation of the compliant die attachment under mold clamping pressure allows complete contact of the mold with the active area, preventing bleeding of the encapsulating material under the edge of a mold portion onto the active area.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
