Patent number: 11264249Abstract: Apparatus, systems, and methods for conducting a hardmask (e.g., carbon containing hardmask) removal process on a workpiece are provided. In one example implementation, a process can include admitting a process gas into a plasma chamber, generating a plasma in the plasma chamber from the process gas using an inductively coupled plasma source, and exposing the carbon containing hardmask to the plasma to remove at least a portion of the carbon containing hardmask. The process gas can include a sulfur containing gas. The process gas does not include a halogen containing gas. The inductively coupled plasma source can be separated from the plasma chamber by a grounded electrostatic shield to reduce capacitive coupling between the inductively coupled plasma source and the plasma.Type: GrantFiled: December 13, 2019Date of Patent: March 1, 2022Assignees: Mattson Technology, Inc., Beijing E-Town Semiconductor Technology Co., Ltd.Inventors: Fen Dai, Tinghao Wang, Oliver D.

Patent number: 10069947Abstract: A method and an apparatus for processing a data packet based on parallel protocol stack instances, where lower-layer protocol processing is performed, using a first protocol stack instance. An associated second protocol stack instance is determined using a target socket after the target socket that is needed to perform upper-layer protocol processing on the data packet is determined, and the upper-layer protocol processing is performed, using the target socket and the second protocol stack instance. The second protocol stack instance that performs the upper-layer protocol processing is determined using the target socket, and hence, a technical problem that protocol processing cannot be performed on a data packet because a protocol stack instance specified by an application (APP) conflicts with a protocol stack instance specified by a network adapter is resolved.Type: GrantFiled: July 28, 2016Date of Patent: September 4, 2018Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yongqiang Yang, Fen Dai, Liufei Wen

Patent number: 6261158Abstract: A multi-step CMP system is used to polish a wafer to form metal interconnects in a dielectric layer upon which barrier and metal layers have been formed. A first polish removes an upper portion of the metal layer using a first slurry and a first set of polishing parameters, leaving residual metal within the dielectric layer to serve as the metal interconnects. A second polish of the wafer on the same platen and polishing pad removes portions of the barrier layer using a second slurry under a second set of polishing parameters. The second polish clears the barrier layer from the upper surface of the dielectric layer, thereby forming the metal interconnect. To reduce dishing and dielectric erosion, the second slurry is selected so that the barrier layer is removed at a faster rate than the residual metal within the dielectric layer. A cleaning step may be optionally performed between the first and second polishes.Type: GrantFiled: December 16, 1998Date of Patent: July 17, 2001Assignee: SpeedFam-IPECInventors: Karey Holland, Ajoy Zutshi, Fen Dai, Yehiel Gotkis, C.
