Abstract
By mounting a semiconductor carrier tray in an accommodating portion of a housing of a burn-in board and then closing a lid member, a large number of semiconductors can be placed on the burn-in board. By putting the burn-in board in this state into a burn-in tester, the plurality of semiconductors can be collectively tested. Accordingly, the semiconductors and sockets for holding the semiconductors need not be provided in the one-to-one relation, whereby a larger number of semiconductors can be tested at once.
