  • Publication number: 20230361042
    Abstract: Partial barrier-free vias and methods for forming such are disclosed herein. An exemplary interconnect structure of a multilayer interconnect feature includes a dielectric layer. A cobalt-comprising interconnect feature and a partial barrier-free via are disposed in the dielectric layer. The partial barrier-free via includes a first via plug portion disposed on and physically contacting the cobalt-comprising interconnect feature and the dielectric layer, a second via plug portion disposed over the first via plug portion, and a via barrier layer disposed between the second via plug portion and the first via plug portion. The via barrier layer is further disposed between the second via plug portion and the dielectric layer. The cobalt-comprising interconnect feature can be a device-level contact or a conductive line of the multilayer interconnect feature. The first via plug portion and the second via plug portion can include tungsten, cobalt, and/or ruthenium.

  • Publication number: 20230290641
    Abstract: The present disclosure provides a method for manufacturing a semiconductor. The method includes: forming a metal oxide layer over a gate structure over a substrate; forming a dielectric layer over the metal oxide layer; forming a metal layer over the metal oxide layer; and performing a chemical mechanical polish (CMP) operation to remove a portion of the dielectric layer and a portion of the metal layer, the CMP operation stopping at the metal oxide layer, wherein a slurry used in the CMP operation includes a ceria compound. The present disclosure also provides a method for planarizing a metal-dielectric surface.

  • Publication number: 20230251722
    Abstract: The present invention relates to a gesture sensing system that uses characteristic point as a positioning starting point to generate coordinate information in space for a test object. The gesture sensing system includes: a light emitter, a light sensor, and a signal processing module. The light emitter emits a plurality of emitted lights to the characteristic point and the test object, and the emitted light is reflected to generate a plurality of reflection light to be received and converted by the light sensor receives into a plurality of sensing signal. Then, the signal processing module generates initial coordinate information and movement coordinate information based on the sensing signals. Finally, the signal processing module generates a gesture according to the initial coordinate information and the change between the movement coordinate information, and executes a preset function according to the movement trajectory of the gesture.
