Latest Patents

Lin Yang holds a patent for a multi-step chemical mechanical polishing system. This innovative CMP system is designed to polish a wafer to form metal interconnects in a dielectric layer. The process involves a first polish that removes an upper portion of the metal layer using a specific slurry and set of polishing parameters. This leaves residual metal within the dielectric layer to serve as the metal interconnects. A second polish is then performed to remove portions of the barrier layer, ensuring that the upper surface of the dielectric layer is cleared, thereby forming the metal interconnect. The selection of slurries and polishing parameters is critical to reduce dishing and dielectric erosion, making her invention a significant advancement in the field.
