Patent number: 8307321Abstract: A method for dummy metal and dummy via insertion is provided. In one embodiment, dummy metals are inserted using a place and route tool, where the place and route tool has timing-awareness. Then, dummy vias arrays are inserted inside an overlap area of dummy metals using a design-rule-checking utility. Fine-grained dummy vias arrays are inserted in available space far away from main patterns. The dummy-patterns resulting from the inserted dummy vias are compressed using the design-rule-checking utility to reduce the size of a graphic data system file generated from the integrated circuit design. The dummy vias can be inserted with relaxed via spacing rules. The dummy metals are inserted with a constant line-end spacing between them for better process control and the maximum length of the dummy metal can be limited for smaller coupling effects. The dummy vias can have various sizes and a square or rectangular shape.Type: GrantFiled: March 22, 2010Date of Patent: November 6, 2012Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Hung-Yi Liu, Chung-Hsing Wang, Chih-Chieh Chen, Jian-Yi Li

Patent number: 8305727Abstract: A joint on an aircraft, the joint comprising: a first component; a second component joined to the first component; and a bonding lead which forms an electrical connection between the components with a resistance between 100 k? and 10 M?. Surprisingly, it has been found that a bonding lead with a relatively high resistance can be used without seriously compromising the static discharge performance of the bonding lead, and that the resulting comparatively low flow of current reduces the risk of sparking in the event of an lightning strike. Bonding leads may be provided as a kit of parts in which at least two of the bonding leads have different lengths and the longer lead is formed from a material having a higher bulk conductivity than the shorter lead. Thus the bonding leads can be made with approximately similar resistances regardless of their lengths.Type: GrantFiled: March 8, 2010Date of Patent: November 6, 2012Assignee: Airbus Operations LimitedInventors: Colin John West, David Alistair Sutton, Robert Bernard Malia, Richard Edward Mills, Alan Donald Pout
