摘要:
A carrier band of electronic parts which can carry electronic parts such as IC packages in good protected condition without spoiling the convenience of a carrier tape having convexities and sticking tape. An electronic parts carrier band T which includes a flexible band (10) and keeps and carries longitudinally at intervals a large quantity of electronic parts (40) where each part (40) has a part body (42) and projecting portions (44) with the carrier band comprising: supporting stands (20), which are mounted longitudinally at intervals and project from the band (10); supporting faces (22), which are formed on the supporting stands (20) and support the electronic parts (40) by contacting the part body (42); opening portions (26), which are opened from the supporting faces (22) to a part of both side faces (24) of the supporting stands (20) at positions corresponding to the part bodies (42); and a sticking tape (30), which is longitudinally affixed to a back side of the band (10) including the supporting faces (22) by a one-sided sticking face (32) of the sticking tape (30), wherein a part of the sticking face (32) is exposed by the opening portions (26) and is stuck to a part body (42).

A device in which the probe sheet is attached to the adhesion holder and a plurality of chips are tested simultaneously by combining the adhesion holder.
摘要:
The fabrication of a semiconductor integrated circuit device involves testing using a pushing mechanism that is constructed by forming, over the upper surface of a thin film probe, a reinforcing material having a linear expansion coefficient (thermal expansion coefficient) almost equal to that of a wafer to be tested; forming a groove in the reinforcing material above a contact terminal; placing an elastomer in the groove so that a predetermined amount projects out of the groove; and disposing a pusher and another elastomer to sandwich the pusher between the elastomers. With the use of such a probe, it is possible to improve the throughput of wafer-level electrical testing of a semiconductor integrated circuit.

摘要:
By using a membrane probe formed by using a manufacturing technique for semiconductor integrated circuit devices, the yield of probing collectively performed on a plurality of chips is to be enhanced. A probe card is formed by using a plurality of pushers, each pusher being formed of a POGO pin insulator, POGO pins, an FPC connector, a membrane probe HMS, an impact easing sheet, an impact easing plate, a chip condenser YRS and so on, wherein one or two POGO pins press a plurality of metal films arranged like islands. One or more cuts are made into what matches the chip to be tested in the area of the membrane probe in a direction substantially parallel to the extending direction of wiring electrically connected to probes formed in the membrane probe.

摘要:
Any damage inflicted on test pads, inter-layer insulating films, semiconductor elements or wiring at the time of electrical inspection of semiconductor integrated circuit devices is to be reduced. Reinforcements having a substantially equal linear expansion ratio (coefficient of thermal expansion) relative to a wafer to be inspected are formed over an upper face of a thin film probe, grooves are cut in the reinforcements above the probes, a first elastomer which is softer than a second elastomer is so arranged as to fill the grooves and overflow the grooves by a prescribed quantity, a glass epoxy substrate, which is a multi-layered wiring board, is fitted over the second elastomer, and pads provided over an upper face of the glass epoxy substrate and bonding pads which are part of wirings belonging to the thin film probe are electrically connected by wires.
