Latest Patents
Among his latest patents, two noteworthy inventions stand out. The first is a **linear polishing apparatus for improving substrate uniformity**. This invention incorporates a novel polishing belt arrangement featuring at least two polishing belts forming a continuous loop. Each belt possesses an outside polishing surface and an inside smooth surface, positioned alongside each other and sharing a common axis at both ends. The design includes a pair of rollers that act as a driver roller and a driven roller, with a platen member positioned between the belts to provide a polishing plane. This innovative setup allows for improved control over the polishing process through the use of independent motors driving each polishing belt.
The second patented invention involves a **method of preserving the top oxide of an ONO dielectric layer via the use of a capping material**. This technology aims to protect and enhance the thickness of the oxidized silicon nitride component within an ONO layer during HF acid-type procedures. The method comprises two approaches: the first involves placing a silicon nitride layer over the ONO layer before pre-clean procedures, while the second employs a polysilicon capping layer that oxidizes during gate oxidation processes, thereby preserving the integrity of the non-volatile memory device.
