Image forming apparatus restricting job execution based on unit price of an electricity charge
It aims to improve user's convenience by, while keeping a printing electricity charge low by executing a print job under a low electricity charge, executing a print job for a user aiming at certain print job execution without waiting until time of the low electricity charge. In order to do so, an image forming apparatus acquires information related to the electricity charge, and restricts execution of the input print job based on the acquired information. Thus, in case of restricting the execution of the input print job based on the information related to the electricity charge, if the input print job is a first print job configured to be executed on a priority basis, the first print job is executed, and, if the input print job is a second print job not configured to be executed on a priority basis, the execution of the second print job is restricted. |

Telephony services optimization through calling plan analysis
Embodiments of the present invention provide optimization of telephone services through telephone calling plan/card analysis. The least expensive rate is found for telephone calls at any given time and/or date, either through static pre-entry of data, or through dynamic querying of rates via a web-based look-up table, and places calls according to an optimized calling plan. Specifically, in a typical embodiment, an outgoing/target telephone number for an intended telephone call is captured, and a corresponding destination geographic region is identified. Based on the geographic region, a calling plan resulting in a lowest price for the telephone call is identified. This is typically accomplished by consulting at least one table (e.g., call information table) that associates (among other things) calling plans and/or calling cards with geographic regions. Once a calling plan and/or calling card is identified/selected, a corresponding set of dialing instructions will be obtained from the table and used to make/place the telephone call. |

Methods and apparatus for processing incomplete or invalid dialed numbers
Calls which fail in the ways described above will typically result in a server (GK, MGC, RS or Ps for example) in the network issuing a failure message. This message typically provides one of two options; call forwarding to a central answering position or call clearing. The message does not allow for any more intelligent decisions to be taken and information about the reason for failure is irretrievably lost. By enhancing the message with an indication of the reason for failure and an optional recommendation for handling, the processing of such failed calls may be improved. For example, a gateway which receives the failure message may simply act in the usual way and either forward or clear the call. However with the enhanced indication, it may instead choose to carry out alternative actions such as collect more digits and retry at end of dial. If overlap signalling is being provided and the IP cloud is not fully overlap compatible, the gateway might also do an overlap to en bloc conversion. Another option is to collect at least one more digit and retry the call. This typically works well if overlap signalling is not used. |

The method also comprises forming at least one first support structure over the first surface of the first integrated circuit package or over a second surface of a second integrated circuit package. The method further comprises mounting the first integrated circuit package over a second integrated circuit package. The first integrated circuit package is mounted over the second integrated circuit package with the first surface facing the second surface, and the at least one first support structure is electrically isolated. |

Thin film transistor including semiconductor oxide layer having reduced resistance regions
A semiconductor device (ST) includes a substrate (11), a gate electrode (12b), a gate insulating film (13b), an oxide semiconductor film (14b) including a channel part (14bc) formed in a position facing the gate electrode (12b), a source electrode (15bs), and a drain electrode (15bd). The source electrode (15bs) and the drain electrode (15bd) is arranged so as not to overlap with the gate electrode (12b) as viewed in the plane. A region adjacent to the gate electrode (12b) and the source electrode (15bs) and a region adjacent to the gate electrode (12b) and the drain electrode (15bd) are, in a region where the source electrode (15bs) and the drain electrode (15bd) does not overlap with the gate electrode (12b), processed such that resistance in a region of the oxide semiconductor film (14b) including a surface thereof is reduced. |

VTFTs including offset electrodes
A device with multiple vertical transistors includes a substrate and an electrically conductive gate structure including first and second edges opposite each other and including first and second reentrant profiles, respectively. A conformal electrically insulating layer maintains the reentrant profiles and is in contact with the gate. A conformal semiconductor layer maintains the reentrant profiles and is in contact with the insulating layer. First and second electrodes are in contact with first and second portions of the semiconductor and adjacent to the first and second reentrant profiles, respectively. A third electrode is in contact with a third portion of the semiconductor on a top of the gate structure. The first and third electrodes and the second and third electrodes define ends of first and second channels of first and second transistors, respectively. First and second lines, extending between the ends of the first and second channels, are not parallel. |

Tuck strategy in transistor manufacturing flow
When forming field effect transistors with a semiconductor alloy layer, e.g., SiGe, embedded in the source/drain regions, a strategy called tucking has been developed in order to improve formation of the semiconductor alloy layer. An improved tucking strategy is hereby proposed, wherein the interface between the isolation region and the active region is not straight, but it rather defines an indentation, so that the active region protrudes into the isolation region in correspondence to the indentation. A gate is then formed on the surface of the device in such a way that a portion of the indentation is covered by the gate. An etching process is then performed, during which the gate acts as a screen. The etching thus gives rise to a cavity defined by a sidewall comprising portions exposing silicon, alternated to portions exposing the dielectric material of the isolation region. |

Method of manufacturing a semiconductor device
The method includes providing a semiconductor chip having a first main face and a second main face opposite the first main face. The semiconductor chip includes an electrical device adjacent to the first main face. Material of the semiconductor chip is removed at the second main face except for a pre-defined portion so that a non-planar surface remains at the second main face. |
