  • Publication number: 20240395618
    Abstract: The present disclosure provides a method for semiconductor fabrication. The method includes receiving a workpiece having gate structures over channel regions on a substrate and source/drain (S/D) features adjacent to the channel regions. The method then forms tungsten S/D contacts over the S/D features in a first ILD layer by a first selective bottom-up metal growth process. The method forms tungsten S/D vias over the tungsten S/D contacts in a second ILD layer by a second selective bottom-up metal growth process. And after forming the tungsten S/D vias, the method forms tungsten gate vias over the gate structures in the first and the second ILD layer. The forming of the tungsten gate vias includes forming a tungsten seed layer by physical vapor deposition (PVD), and depositing tungsten directly on horizontal and sidewall surfaces of the tungsten seed layer by chemical vapor deposition (CVD).

  • Publication number: 20240345491
    Abstract: A system for monitoring and controlling an EUV light source includes a first temperature sensor, a signal processor, and a process controller. The first temperature sensor includes a portion inserted into a space surrounded by a plurality of vanes through a vane of the plurality of vanes, and obtains an ambient temperature that decreases with time as a function of tin contamination coating on the inserted portion. The signal processor determines an excess tin debris deposition on the vane based on the obtained chamber ambient temperature. The process controller activates a vane cleaning action upon being informed of the excess tin debris deposition by the signal processor, thereby improving availability of the EUV light source tool and reducing risks of tin pollution on other tools such as a reticle.
