Abstract:
A probe card is disclosed that includes a board having a first surface and a second surface facing away from each other and a through hole formed between the first and second surfaces; and a probe needle having a penetration part and a support part. The penetration part is placed in the through hole without contacting the board and projects from the first and second surfaces of the board. The support part is integrated with a first one of the end portions of the penetration part and connected to one of the first and second surfaces of the board. The support part has a spring characteristic. The penetration part is configured to have a second one of its end portions come into contact with an electrode pad of a semiconductor chip at the time of conducting an electrical test on the semiconductor chip.
Abstract:
A storage system capable of identifying all volumes to be audited is provided.Operation logs 3005 concerning the operations of volumes are associated with a time and stored in storage apparatuses 1400 and 1500, and a management computer 1100 collects information about these operation logs 3005, restores the status history of the operation logs 3005, sets, as an audit range, the operation logs 3005 including volumes with an audit period and audit target data stored therein, extracts the operation logs 3005 belonging to the audit range from the restored status history of the operation logs 3005, and transmits the extracted operation logs 3005 to a computer (requesting computer) 1000. As a result, all the audit target volumes can be identified.
Abstract:
A wiring board adapted for mounting an electronic component has the form of a structure in which a plurality of wiring layers are stacked one on top of another with an insulating layer interposed therebetween and are interconnected through via holes formed in the insulating layers, respectively. A plurality of openings are formed through the structure in a region where a wiring is not formed, extending through the structure in a thickness direction thereof. Further, solder resist layers are formed on the outermost wiring layers, respectively, and exposing pad portions defined in desired locations in the outermost wiring layers.
Abstract:
A semiconductor package including a base body having a recessed portion for installing an electronic component on one surface, the recessed portion including an inner bottom surface, inclined surface and a shoulder part and a wiring pattern having one end positioned in the inner bottom surface of the recessed portion and the other end extending to an outside region of the recessed portion beyond the shoulder part of the recessed portion. The shoulder part of the recessed portion is a smoothly curved surface.
Abstract:
Provided is a computer system, including: a computer; and a storage system coupled to the computer via a network. The computer includes: an interface coupled to the network, a processor coupled to the interface and a memory coupled to the processor. The storage system includes a plurality of volumes in which files are stored. The processor is configured to: decide duplicating files from among the files stored in the plurality of volumes as files to be consolidated; identify a plurality of volumes in which the files to be consolidated are stored; select at least one volume from among the identified plurality of volumes as a consolidation volume based on loads imposed on the identified plurality of volumes; and delete the files to be consolidated stored in the volumes that are not selected. Accordingly, in data de-duplication, it is possible to avoid extra loads from centralizing in a high-load-bearing volume.
Abstract:
The present disclosure relates to a method of manufacturing a substrate. The method includes: (a) forming through holes by applying an anisotropic etching to a silicon substrate from a first surface of the silicon substrate; (b) forming a first insulating film to cover the first surface of the silicon substrate, surfaces of the silicon substrate exposed from the through holes, and a second surface of the silicon substrate opposite to the first surface; (c) forming an opening in a portion of the first insulating film provided on the second surface, the portion of the first insulating film corresponding to an area in which the through holes are formed; (d) etching the silicon substrate using the first insulating film provided on the second surface as a mask, thereby forming a cavity in the silicon substrate; and (e) removing the first insulating film.
Abstract:
Creating a plaintext index from a text that is extracted from a file presents the risk of a leak of confidential information from the created index. To address this problem, provided is a computer system which has a computer, a storage subsystem coupled to the computer, and a network coupling the computer and the storage subsystem. The computer has an interface coupled to the network, a first processor coupled to the interface, and a memory coupled to the first processor. The storage subsystem has a disk device which stores data. A storage area of the disk device is divided into a plurality of storage areas including, at least, a first storage area and a second storage area. The first processor reads a part of data stored in the first storage area, encrypts the part of data read from the first storage area when the data stored in the first storage area is judged as encrypted data, and writes the encrypted part of data in the second storage area.
