Abstract
Abstract The present invention includes integrated circuit packages, ball-grid array integrated circuit packages and methods of packaging an integrated circuit. One aspect of the present invention provides an integrated circuit package including a substrate having opposing first and second substrate surfaces and at least one electrical connection supported by the first substrate surface and adapted to couple with circuitry external of the package; a semiconductor die including circuitry electrically coupled with the at least one electrical connection; a first die surface coupled with the second substrate surface; a second die surface; and a cover coupled with the second die surface. Another aspect of the present invention includes a method of packaging an integrated circuit including providing a semiconductor die having circuitry; providing a substrate having at least one electrical connection; electrically coupling the circuitry of the semiconductor die with the at least one electrical connection; providing a cover; and covering a surface of the semiconductor die using the cover, the covering including contacting the solid cover with the semiconductor die surface.
