  • Publication number: 20240387660
    Abstract: An interconnect fabrication method is disclosed herein that utilizes a disposable etch stop hard mask over a gate structure during source/drain contact formation and replaces the disposable etch stop hard mask with a dielectric feature (in some embodiments, dielectric layers having a lower dielectric constant than a dielectric constant of dielectric layers of the disposable etch stop hard mask) before gate contact formation. An exemplary device includes a contact etch stop layer (CESL) having a first sidewall CESL portion and a second sidewall CESL portion separated by a spacing and a dielectric feature disposed over a gate structure, where the dielectric feature and the gate structure fill the spacing between the first sidewall CESL portion and the second sidewall CESL portion. The dielectric feature includes a bulk dielectric over a dielectric liner. The dielectric liner separates the bulk dielectric from the gate structure and the CESL.

  • Publication number: 20140075491
    Abstract: The method is applied to the recording device, and the recording device is connected to a set-top box. The error proof method includes following steps. In the beginning, whether a startup process of the set-top box has been finished is determined according to a video signal and an audio signal outputted from the set-top box. After the startup process of the set-top box is finished, the video signal outputted from the set-top box is analyzed to determine whether an image of the video signal is covered by an information window. If the image of the video signal is not covered by any information window, then a channel changing signal is transmitted to the set-top box, to change a channel of the set-top box to a reserved recording channel. After that, a television program of the reserved recording channel is recorded.
