摘要： This application provides a multicast broadcast service sending method, an apparatus, and a system, so that a multicast broadcast service can be properly configured and sent when a receiver of the multicast broadcast service includes a narrowband terminal and a broadband terminal, to reduce resource overheads as much as possible. The method includes: An access network device receives indication information from a core network device, learns that a receiver of a target multicast broadcast service includes a narrowband terminal and a broadband terminal, sends an MCCH to the narrowband terminal and the broadband terminal, and sends a multicast broadcast service to the narrowband terminal and the broadband terminal on a frequency domain resource corresponding to an MTCH of the target multicast broadcast service. Configuration information of the MTCH is carried in the MCCH. Correspondingly, after receiving the MCCH, the narrowband terminal and the broadband terminal receive the target multicast broadcast service on the frequency domain resource corresponding to the MTCH. A first frequency domain resource corresponding to the MCCH or a scheduling bandwidth occupied by the MCCH does not exceed a maximum bandwidth capability of the narrowband terminal.

摘要： This application discloses a semiconductor chip, a production method therefor, and an electronic device. The semiconductor chip includes a substrate and a Fin FET located on the substrate. The Fin FET includes a fin, two sidewalls that extend across the fin and are arranged opposite to each other, and a gate structure located in a trench defined by the two sidewalls. The gate structure includes a gate dielectric layer and a gate metal layer that are stacked in sequence. The gate metal layer includes a TiSiN layer. To be specific, a TiSiN material is used to fill a gap. During filling with TiSiN, a lattice structure of TiN may be damaged due to doping of Si, so that a formed TiSiN thin film becomes an amorphous thin film, to prevent ahead-of-time sealing of a gap opening due to an excessively large grain size. Therefore, the TiSiN layer in the gate structure provided in this application has an excellent gap filling capability, and can implement seamless filling of a gap with a high depth-width ratio. In addition, TiSiN with a low silicon concentration has a resistivity similar to or even lower than that of TiN. Therefore, a low-resistivity gate structure can be implemented.
