  • Patent number: 12327715
    Abstract: A magnetic shield reduces external noise in a chamber including a target and at least one electromagnet for copper physical vapor deposition (PVD). The shield may have a thickness in a range from approximately 0.1 mm to approximately 10 mm to provide sufficient protection from radio frequency and other electromagnetic signals. As a result, copper atoms in the chamber undergo less re-direction from external noise. Additionally, even when hardware failure occurs during PVD (e.g., an electromagnet malfunctions, a wafer stage is not level, and/or a flow optimizer induces too much shift, among other examples), the copper atoms are less susceptible to small re-directions from external noise. As a result, back end of line (BEOL) and/or middle end of line (MEOL) conductive structures are formed in a more uniform manner, which increases conductivity and improves lifetime of an electronic device including the BEOL and/or MEOL conductive structures.

  • Publication number: 20240008294
    Abstract: The present invention relates to an organic thin film transistor (OTFT) comprising an organic semiconductor layer (2) arranged between a source terminal (3) and a drain terminal (4). The OTFT further includes a front gate (5) electrode arranged on one side of the organic semiconductor layer and a back gate electrode (6) arranged on the opposite side of the organic semiconductor layer. The front and back gate electrodes are arranged to control the current flow in the organic semiconductor layer upon application of a voltage and the back gate electrode is electrically connected to one of: the front gate electrode and the source terminal. OTFT's according to the present invention, with a connection between the back gate and the source or front gate, exhibit improved turn on voltage stability, lower power consumption and improved bias stress stability compared to single gate and back gate isolated OTFTs.

  • Patent number: 10104643
    Abstract: A method of managing bandwidth resources provided by multiple network interfaces is proposed. When one or more network interfaces provide network bandwidth resources, a bandwidth manager manages all available bandwidth resources based on a list of decision criteria. The list of decision criteria includes energy efficiency, network throughput, channel condition, device mobility, and user preference. An application traffic flow distributor dynamically adjusts the amount of traffic flows on different network interfaces according to the joint decision based on the decision criteria. A network interface manager dynamically enables or disables each network interface according to the joint decision based on the decision criteria. Furthermore, a device movement analyzer analyzes and predicts device movement to facilitate accurate decision making of the bandwidth management.

    Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. In one embodiment, the access information comprises mapping information between the TMGI and the communication group ID.
