A semiconductor substrate eliminates a restriction caused by a width of scribe lines so as to increase a number of semiconductor elements formed on the semiconductor substrate. A plurality of semiconductor element areas are formed by forming a plurality of unit exposed and printed areas, each of which contains the semiconductor element areas. A first scribe line extends between the semiconductor element areas formed within the unit exposed and printed area. A second scribe line extends between the unit exposed and printed areas. A width of the first scribe line is different from a width of the second scribe line.

An electronic component attaching tool suitable for an external shape of a semiconductor device is prepared. The electronic component attaching tool has a function of aligning a position of the semiconductor device to an IC socket. The electronic component attaching tool is mounted on the standard surface that is formed on the IC socket substantially regardless of the external shape of the semiconductor device. The semiconductor device is then aligned and attached to the IC socket by using the electronic component attaching tool, and the electronic component attaching tool is removed from the IC socket. Another electronic component attaching tool suitable for an external shape of another semiconductor device is prepared, and the same procedure as the above is performed to align and attach this semiconductor device to the same type IC socket.

A contactor has contact electrodes elastically deformable in a direction of thickness of the contactor so that the contactor can make a contact with a semiconductor device with an appropriate contact pressure. The contactor is positioned between the semiconductor device and a test board so as to electrically connect the semiconductor device to the test board. Each of a plurality of contact electrodes has a first contact electrode part, a second contact electrode part and a connecting part electrically connecting the first contact electrode part to the second contact electrode part. The first contact electrode part contacts an electrode of the semiconductor device. The second contact electrode part contacts a terminal of the test board. A combining member has an insulating characteristic and holds the connecting part of each of the contact electrodes in a predetermined arrangement.

A semiconductor device has an alignment mark which can be recognized by a conventional wafer prober. A redistribution layer connects electrodes of the semiconductor device to electrode pads located in predetermined positions of the redistribution layer. Metal posts configured to be provided with external connection electrodes are formed on the electrode pads of the redistribution layer. A mark member made of the same material as the metal posts is formed on the redistribution layer. The mark member serves as an alignment mark located in a predetermined positional relationship with the metal posts.

An LSI package comprises an LSI element and a wiring board. The plurality of pin terminals of the LSI element each includes a first conductive layer and a second conductive layer superposed on the first conductive layer. The plurality of pin terminals of the wiring board each includes a third conductive layer joined to the second conductive layer, and the wiring board further comprises outer joining terminals. The first, second, and third conductive layers are made of materials causing the metallic bond between the second conductive layer and third conductive layer to be stronger than the metallic bond between the first conductive layer and second conductive layer. The LSI element is tested using the outer joining terminals of the wiring board. The second conductive layer and third conductive layer are joined to attain a metallic bond through aggregation derived from pressure, and are reliably brought into electrical contact with each other for a test. After the test is completed, the terminals of the LSI element are peeled off from the terminals of the wiring board. At this time, the second conductive layer is transferred to the third conductive layer, and the first conductive layer is left intact in each of the terminals of the LSI element. The LSI element is then mounted on another wiring board.
