    摘要: A method of fabricating an interconnect structure (e.g., dual damascene interconnect structure, and the like) of an integrated circuit device is disclosed. The interconnect structure is fabricated using a bi-layer mask comprising an imaging film and an organic planarizing film. The bi-layer mask is used to remove lithographic misalignment between a contact hole, a trench, and an underlying conductive line when the interconnect structure is formed. Additionally, a sacrificial layer may be used to protect an inter-metal dielectric (IMD) layer during subsequent planarization of the interconnect structure. The sacrificial layer may be formed of amorphous silicon (Si), titanium nitride (TiN), tungsten (W), and the like. The interconnect structure may be formed of a metal (e.g., copper (Cu), aluminum (Al), tantalum (Ti), tungsten (W), titanium (Ti), and the like) or a conductive compound (e.g., tantalum nitride (TaN), titanium nitride (TiN), tungsten nitride (WN), and the like).

    摘要: A high priority service sending method and device in a direct mode, and a high priority service receiving method and device in a direct mode. The receiving method includes: after sending a voice frame in a voice call sending state, a user terminal receiving and detecting a priority frame in another time slot with respect to the time slot occupied by the voice call; and if the priority frame is detected, then stopping the voice call and receiving a high priority service frame in the other time slot. Using the present invention can enable an interphone in a transmitting state in a direct mode to send or receive a high priority service as well.

    摘要: A method for patterning a wafer using a phase shifting photolithography that can produce a critical symmetrical 2-dimensional structure such as a magnetic write pole of a magnetic write head. In one aspect of the invention, a photolithographic mask has an opaque portion with narrow, transparent phase shifting regions at either side of the opaque portion. A non-phase shifted region extends beyond the narrow phase shifted portion at either side of the structure. The phase shifted regions are symmetrical about the opaque region so that the image produced on the wafer is completely symmetrical. In another aspect of the invention, a phase shifted region in formed in a transparent medium with non-phase shifted regions at either side of the phase shifted region. The transition between the phase shifted region and non-phase shifted region alone defines a pattern on the wafer, without the need for an opaque structure on the mask.
