Patent number: 7398509Abstract: A computer network for generating instructions for photomask manufacturing equipment, based on photomask specification data input by a customer. A series of order entry screens are downloaded to a remote customer's computer, typically via an internet connection. The customer is prompted to enter photomask specification data, which is delivered to computing equipment on the manufacturer's local network. The manufacturer's computing equipment validates the photomask specification data, and uses this data to generate fracturing instructions and equipment control instructions. The fracturing instructions, together with pattern design data from the customer, are delivered to a fracture engine, which provides fractured pattern data. The control instructions and the fractured pattern data may then be electronically delivered to the manufacturing equipment.Type: GrantFiled: November 18, 2005Date of Patent: July 8, 2008Assignee: Toppan Photomasks, Inc.Inventors: Jeffry S. Schepp, Jan E. Gentry, Thomas T. Cogdell

Patent number: 6978437Abstract: A photomask for eliminating antenna effects in an integrated circuit and integrated circuit manufactured with the photomask are disclosed. The photomask includes a substrate and a patterned layer formed on at least a portion of the substrate. The patterned layer may be formed using a mask pattern file created by analyzing a pattern in a mask layout file to identify a region including an antenna ratio less than a first design rule.
