Abstract:
As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

Abstract:
A probe having a sufficient height is manufactured by selectively depositing, over the main surface of a wafer, a copper film in a region in which a metal film is to be formed and a region which will be outside an adhesion ring when a probe card is fabricated; forming the metal film, polyimide film, interconnect, another polyimide film, another interconnect and a further polyimide film; and then removing the wafer and copper film. According to the present invention, when probe testing is performed using a prober (thin film probe) having the probe formed in the above-described manner while utilizing the manufacturing technology of semiconductor integrated circuit devices, it is possible to prevent breakage of the prober and a wafer to be tested.
Abstract:
A semiconductor chip inspection apparatus largely reduces occurrence of damage due to foreign matter in an inspection process and improves durability at the same time of miniaturization is provided. As to a highly accurate thin-film probe sheet which performs: a contact to electrode pads arranged at a narrow pitch and a high density along with integration of semiconductor chip; and an inspection of semiconductor chips, by providing two layers of metal films selectively removable in a step-like shape in a periphery region of fine contact terminal having sharp tips and arranged at a high density and a narrow pitch at the same level as electrode pads, an upper periphery of the contact terminals is covered with an insulating film, and a large space region is formed.
Abstract:
As the thickness of the card holder for preventing warping of a multilayered wiring substrate 1 is increased, there occurs a problem that a thin film sheet 2 is buried in a card holder and secure contact between probes 7 and test pads cannot be realized. For its prevention, the thin film sheet 2 and a bonding ring 6 are bonded in a state where a tensile force is applied only to the central region IA of the thin film sheet 2, and a tensile force is not applied to an outer peripheral region OA. Then, the height of the bonding ring 6 defining the height up to the probe surface of the thin film sheet 2 is increased, thereby increasing the height up to the probe surface of the thin film sheet 2.
Abstract:
A technique of manufacturing a semiconductor integrated circuit device is provided for reducing the possibility of attachment of foreign matter to a membrane probe when performing probe inspection using the membrane probe formed by the manufacturing technique. A pressing member for pressing a membrane sheet includes a pressing pin receiving portion relatively disposed above for receiving the tip of a pressing pin of the plunger in a recess, and a membrane sheet pressing portion relatively disposed below. The membrane sheet pressing portion in contact with the membrane sheet has the minimum plane size to enable pressing of the entire surface of one chip of interest to be subjected to the probe inspection.
Abstract:
A probe is contacted to a test pad, without destroying the circuit formed in the chip at the time of a probe test. Therefore, a load jig, a pressing tool, an elastomer, an adhesion ring, and a plunger are made into one by fixation with a nut and a bolt. The elastic force of the spring installed between the spring retaining jig and the load jig acts so that the member used as these one may be depressed toward pad PD. The thrust transmitted from the spring in a plunger to a thin films sheet is used only for the extension of a thin films sheet.
