Integrated circuit device having an improved package structure.

摘要

An integrated circuit device includes a package (11, 41) having first and second surfaces and first and second internal connection lines (13b, 41b). A semiconductor integrated circuit chip (16) is mounted on the first surface of the package. A first group of external connection terminals (15) is provided on the first surface of the package, and is electrically connected to the semiconductor integrated circuit chip through the first internal connection lines (13b). A second group of external connection terminals (18) is provided on the second surface of the package so as to form a matrix arrangement of terminals, and is electrically connected to the semiconductor integrated circuit chip through the second internal connection lines (41b). The second group of external connection terminals includes specific terminals (18-2) specifically passing signals to be supplied to or from the semiconductor integrated circuit chip. The signals passing through the specific terminals are signals used at the time of evaluating the semiconductor integrated circuit chip.
