Patent ID: 8323992

Claim:
A method of manufacturing a semiconductor integrated circuit device, the method comprising the steps of: (a) preparing a semiconductor wafer, which is partitioned into a plurality of chip regions, in which a semiconductor integrated circuit is formed in each of the plurality of chip regions, and on whose principal surface a plurality of chip electrodes are electrically connected to the semiconductor integrated circuit; (b) preparing a first card including a wiring substrate, a first sheet, and a pressing portion, the wiring substrate on which a plurality of first wirings are formed, the first sheet including: a plurality of contact terminals to be contacted to the plurality of chip electrodes; a contact-terminal formation surface on which the plurality of contact terminals are formed; and a rear surface positioned on an opposite side to the contact-terminal formation surface, and the first sheet being retained on the wiring substrate so that tips of the plurality of contact terminals face the principal surface side of the semiconductor wafer, and the pressing portion pressing a contact-terminal arrangement region of the first sheet, where the plurality of contact terminals are formed, from the rear surface via a buffer layer; and (c) performing electrical inspection for the semiconductor integrated circuit by contacting the tips of the plurality of contact terminals of the first sheet to the plurality of chip electrodes of the semiconductor wafer, the first sheet including: a first insulating film including the contact-terminal formation surface; a plurality of second wirings formed between the first insulating film and the rear surface, and electrically connected to the plurality of first wirings and the plurality of contact terminals, respectively; and a second insulating film including the rear surface, and formed on the first insulating film and the plurality of second wirings, the plurality of contact terminals including a plurality of first contact terminals formed in a first contact terminal group arranged along a first direction in a plan view, the plurality of second wirings connected to the plurality of first contact terminals among the plurality of second wirings being arranged so as to be extended along a direction intersecting with the first direction in a plan view, a third wiring formed on the first insulating film along the plurality of second wirings and not electrically connected to the plurality of contact terminals being arranged on an opposite side to the first contact terminal group of the first contact terminal arranged at an end portion of the first contact terminal group among the plurality of first contact terminals in a plan view, and a slit formed of an opening portion penetrating from one surface among the contact-terminal formation surface and the rear surface of the first sheet to the other surface being formed along the plurality of second wirings between the first contact terminal arranged at the end portion of the first contact terminal group and the third wiring.
