Abstract: An n-type metal oxide semiconductor transistor includes a gate structure, two source/drain regions, two amorphous portions and a silicide. The gate structure is disposed on a substrate. The two source/drain regions are disposed in the substrate and respectively located at two sides of the gate structure, wherein at least one of the source/drain regions is formed with a dislocation. The two amorphous portions are respectively disposed in the two source/drain regions. The silicide is disposed on the two source/drain regions, wherein at least one portion of the silicide overlaps the two amorphous portions.

Abstract: Methods, systems, and computer program products for integrating roaming control in a signaling message routing node are disclosed. In one exemplary implementation, a method for providing roaming control at a signaling message routing node is provided. The method includes receiving a signaling message at a signaling message routing node in a network of a home service provider of a mobile subscriber, the signaling message being generated in response to the mobile subscriber registering in a foreign carrier's network. It is determined whether the mobile subscriber is allowed, by the home service provider, to roam in the foreign carrier's network. In response to determining that mobile subscriber is not allowed to roam in the foreign carrier's network, a response to the signaling message is generated and sent, where the response indicates that mobile subscriber is not allowed to roam in a foreign carrier's network. The steps of the method are performed at a signaling message routing node.

Abstract: Methods, systems, and computer program products for offloading prepaid credit status queries from prepaid credit status databases for unlimited-plan prepaid in-network calls is provided. According to one aspect, the subject matter described herein includes a method that includes intercepting, at a signaling message routing node, a prepaid status query associated with a call originated by a calling subscriber and directed to a called subscriber. The signaling node then determines whether the calling subscriber is associated with an unlimited calling plan, unlimited text messaging plan, unlimited multimedia messaging plan, or a combination of plans based on the intercepted prepaid status query. The node also determines whether the call is an in-network call based on the intercepted prepaid status query, where an in-network call includes a call between a calling subscriber and a called subscriber belonging to the same network.
