Abstract
A semiconductor package includes: a substrate having an upper surface and a lower surface; an integrated circuit chip having bond pads; a lid attached on the upper surface of the substrate so as to cover the chip; and one or more projections that electrically connect the lid to a plurality of ground patterns. The substrate has substrate pads formed on the upper surface, and one or more of the substrate pads extend to form the ground patterns. The chip is bonded on the upper surface of the substrate. One or more of the bond pads are ground bond pads, and the bond pads are electrically connected to the corresponding substrate pads. An electrically nonconductive adhesive is used for the attachment of the lid to the substrate, and the projections are connected to the ground patterns by an electrically conductive adhesive. The ground projections are positioned at four corners of a cavity that is formed between the substrate and the lid. The semiconductor package further includes: external connection terminals formed on the lower surface of the substrate and electrically connected to the corresponding substrate pads; and a thermal interface material is interposed between lid and the chip, the thermal interface material transmitting heat generated by the chip to the lid.

Important Notes on Latency of Status data
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.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
