摘要:
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.

A testing device can perform a test on an arbitrary one of a plurality of semiconductor devices by pressing the semiconductor devices onto a contactor from a back side of the semiconductor device. A test circuit board has a contactor provided with contact pieces corresponding to external connection terminals of semiconductor devices to be tested. A support board is capable of mounting the semiconductor devices thereon in an aligned state. A stage supports the support board. A press head presses the semiconductor devices to be tested mounted on the support board so as to cause external connection terminals of the semiconductor devices to be tested to contact with the contact pieces of the contactor. The stage is movable to a position at which at least one of the semiconductor devices to be tested, which are mounted on the support board, faces the contactor.

A contactor for electronic parts can provide an appropriate and uniform contact with respect to a plurality of electrode terminals in an electronic part such as an IC. Each of a plurality of contact members has a first contact portion on one end thereof and a second contact portion on the other end thereof, the first contract portion having a recessed portion that receives one of the electrode terminals of the electronic part. A base accommodates and supports the plurality of the contact members. The first contact portion is movable in a horizontal direction.

A probe card that is manufactured inexpensively. The probe card includes a base plate, a flexible substrate, and a contact probe. The contact probe is a flexible substrate formed from polyimide resin. The contact probe has a plurality of parallel wires. Each wire has a distal end that functions as a contact. The contact probe is produced by cutting a general purpose substrate having a plurality of parallel wires formed at a predetermined pitch. The number of the parallel wires is equal to the number of pads of an LSI chip.
