Latest Patents

One of his latest patents focuses on the attenuation of reflecting lights by surface treatment. This method aims to avoid resist notching during the formation of a polysilicon gate electrode in integrated circuit devices. The process involves creating bare active areas surrounded by field oxide isolation on a semiconductor substrate. The uneven topography of the substrate is addressed by roughening a polysilicon layer using a plasma etching process, which forms pits that act as light traps. This innovative approach ensures that reflection lights from actinic light do not interfere with the unexposed portions of the photoresist layer, resulting in a notch-free photoresist mask.

Another notable patent by Ron-Fu Chu is related to a Chemical-Mechanical Polish (CMP) planarizing method and slurry composition. This invention provides a solution for planarizing copper metal and copper metal alloy layers within integrated circuits. The method employs a specially formulated CMP slurry composition that includes a non-aqueous coordinating solvent and a halogen radical producing species, ensuring effective planarization of the substrate layers.
