Abstract
This invention discloses a semiconductor package with adhesive material pre-printed on the lead frame and chip, and the manufacturing method. The adhesive material is applied onto the chip carrier and the pin of the lead frame and also on the front electrode of the semiconductor chip via pre-printing. The back of the semiconductor chip is adhered on the chip carrier, and the front electrode of the semiconductor chip and the pin are connected respectively with a metal connector. The size, shape and thickness of the adhesive material are applied according to different application requirements according to size and shapes of the contact zone of the semiconductor chip and the metal connector. Particularly, the adhesive zones are formed by pre-printing the adhesive material thus significantly enhance the quality and performance of semiconductor products, and improves the productivity.

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.
