Redundantly tied metal fill for IR-drop and layout density optimization

An integrated circuit and a method for using metal fill geometries to reduce the voltage drop in power meshes. Metal fill geometries are connected to the power mesh using vias or wires at multiple locations. Metal fill geometries are connected to other floating metal fill geometries using vias or wires at multiple locations. The circuit design introduces maximum redundancy between metal fill geometries and power mesh geometries, but partial redundancy between metal fill geometries and metal fill geometries. In particular, the redundancy in connectivity between metal fill geometries and metal fill geometries is kept minimal to reduce the number of geometries introduced. The high redundancy between metal fill geometries and power mesh geometries and the partial redundancy among metal fill geometries result in a smaller IR-drop by reducing the effective resistance on a power mesh. Hence, the invention use redundancy carefully and advantageously to achieve simultaneous metal density and IR-drop optimization without introducing excessive number of metal fill geometries.

Pattern matching method and apparatus

When the degree of matching between patterns decreases due to a pattern fluctuation or an appearance fluctuation that has occurred during manufacturing steps, a heavy work burden would be placed on an operator. A data processing unit of a pattern matching apparatus calculates a threshold for determination of matching between a first template image and a partial region of a search target image obtained by capturing an image of the surface of a sample, on the basis of a result of evaluation of a similarity between the search target image and a second template image, the second template image having been captured in a wider range than the first template image.

Content distribution method and relay apparatus

A relay apparatus 30 issues a new sub-address at a timing when mobile phones (10a, 10b) requested content from a CP server apparatuses (20a, 20b), that is, at a timing when a sub-address is required. The content specified by this sub-address is distributed from the CP server apparatuses via the relay apparatus (30) to the mobile phones. In system of the present invention it is possible to utilize the same sub-address many times for different content items. It is therefore possible to avoid increasing the number of digits of the sub-address as well as the complexity of the sub-address structure, in a case where the types of content or the number of content items increases.

Semiconductor device, method of manufacturing the same, and phase shift mask

A main wall part is provided so as to surround an integrated circuit part. A sub-wall part which is in “L” shape is provided between each corner of the main wall part and the integrated circuit part. Therefore, even if the stress is concentrated due to heat treatment or the like, the stress is dispersed to the main wall part and the sub-wall part, and hence peeling between layers and a crack are unlikely to occur, as compared with the conventional art. Further, even if the crack and the like occur at the corner, moisture from the outside hardly reaches the integrated circuit part when the main wall part and the sub-wall part are coupled to each other. For this reason, it is possible to ensure an extremely high moisture resistance.
