Abstract
Manufacturing of semiconductor devices is facilitated when the device chip carriers of the devices are tested, prior to population of chips thereon, by a module test card. The module test card is formed by a test substrate and a plurality of test chips mounted on the test substrate. Connections are provided on the test substrate for connecting to a tester. Through the module test card, the device chip carriers are tested under simulation of their operating conditions.
