Latest Patents

Chih-Chin Yang holds a patent for a planarization method applied in the process of manufacturing semiconductor components. This method involves forming a dielectric layer above a substrate, which defines a trench. A barrier layer and a metal layer are sequentially formed within the trench. The first planarization process utilizes a first reactant to remove a portion of the metal layer, ensuring that the etching rate of the first reactant to the metal layer is greater than that to the barrier layer. Subsequently, a second planarization process is applied using a second reactant, which removes portions of both the barrier layer and the metal layer to expose the dielectric layer. The etching rate of the second reactant to the barrier layer is greater than that to the metal layer.
