Latest Patents

One of Yi Zhou's latest patents is titled "Integrated cleaning process for substrate etching." This innovative method addresses the challenge of removing etchant byproducts from an etch reactor while discharging a substrate from an electrostatic chuck. The process involves etching one or more layers on a substrate that is electrostatically secured within the chamber of the etch reactor using a first plasma. This generates etchant byproducts, which are then managed through a second plasma treatment that trims the photoresist and removes a portion of the byproducts. The method ensures that the substrate can be effectively discharged from the chamber after the etching process is complete.

Another notable patent is focused on "Chamber processes for reducing backside particles." This patent outlines methods for semiconductor processing that include performing plasma treatments to remove carbon-containing and silicon-containing materials within a processing chamber. The innovative techniques aim to enhance the cleanliness and reliability of semiconductor manufacturing processes.
