Latest Patents

Yehiel Gotkis holds a patent for a multi-step chemical mechanical polishing system. This system is designed to polish a wafer to form metal interconnects in a dielectric layer, upon which barrier and metal layers have been formed. The first polish removes an upper portion of the metal layer using a specific slurry and set of polishing parameters, leaving residual metal within the dielectric layer to serve as the metal interconnects. The second polish, performed on the same platen and polishing pad, removes portions of the barrier layer using a different slurry and set of parameters. This innovative approach reduces dishing and dielectric erosion, ensuring a more efficient and effective polishing process.
