Title: Methods of forming power semiconductor devices using boule-grown silicon carbide drift layers, and power semiconductor devices formed by the method
Inventor: SUMAKERIS JOSEPH JOHN
IPC: H01L21/337
Filed: 2012-02-02
Abstract: PROBLEM TO BE SOLVED: To resolve a problem that, notwithstanding the preferred electrical characteristics of silicon carbide, there continues to be a need for silicon carbide power devices having thicker voltage supporting regions therein.SOLUTION: Methods of forming high voltage silicon carbide power devices utilize high purity silicon carbide drift layers that are derived from high purity silicon carbide wafer material, instead of prohibitively costly epitaxially grown silicon carbide layers. The methods include forming both minority carrier and majority carrier power devices that can support greater than 10 kV blocking voltages, using drift layers having thicknesses greater than about 100 μm. The drift layers are formed as boule-grown silicon carbide drift layers having a net n-type dopant concentration therein that is less than about 2×10cm. These n-type dopant concentrations can be achieved using neutron transmutation doping (NTD) techniques.

Title: Wireless communication method and apparatus reporting traffic volume measurement information for supporting enhanced uplink data transmission
Inventor: ZHANG GUODONG
IPC: H04L12/56
Filed: 2012-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication method and an apparatus for reporting traffic volume measurement (TVM) information which is used for supporting enhanced uplink (EU) data transmission between a wireless transmit/receive unit (WTRU) and a node-B.SOLUTION: After storing the EU data in a buffer, the WTRU transmits an initial TVM information request message, which shows that the buffer has the EU data, to the node-B. In response to this, the node-B schedules one or more permitted EU data transmission. The WTRU transmits at least one portion of the stored EU data to the node-B through the permitted EU data transmission. In one embodiment, only when the volume of the EU data stored in the buffer of the WTRU exceeds the set threshold value, the initial TVM information request message is transmitted. However, when the volume does not exceed, scheduling is not requested and all the stored EU data is transmitted to the node-B.
