Publication number: 20040268249Abstract: In a server a source document is represented as a source document object model (13). For delivery of the source document to a user device such as a mobile phone the server dynamically selects transformation maps (10) and merges them to provide a compound map (12). The maps (10) are selected according to characteristics of the delivery channel and of the user device. The source DOM (13) is then transformed into a target DOM (14) in a single pass. Each node of the source DOM (13) self-transforms using the map rules. At the node level the transformation may change node attributes and/or node-to-node relationships.Type: ApplicationFiled: July 30, 2004Publication date: December 30, 2004Inventors: Thomas Fennelly, Ronan Charles Brady, Ronan John Geraghty, Rotan Hanrahan

Patent number: 6670242Abstract: A method for making an integrated circuit device includes forming source and drain regions in a semiconductor substrate and defining a channel region therebetween, forming a graded, grown, gate oxide layer adjacent the channel region, forming a nitride layer adjacent the gate oxide layer, and forming a gate electrode layer adjacent the nitride layer. The gate oxide layer may be formed by growing a first oxide portion by upwardly ramping the channel region to a first temperature lower than a glass transition temperature, and exposing the channel region to an oxidizing ambient at the first temperature and for a first time period. A second oxide portion may be grown between the first oxide portion and the channel region by exposing the channel region to an oxidizing ambient at a second temperature higher than the glass transition temperature for a second time period so that the second oxide portion has a thickness in a range of about 2% to about 75% of a total thickness of the gate oxide layer.Type: GrantFiled: August 30, 2000Date of Patent: December 30, 2003Assignee: Agere Systems Inc.Inventors: David Charles Brady, Yi Ma, Pradip Kumar Roy
