Latest Patents

Two of Kanekiyo's latest patents demonstrate his ingenuity in enhancing plasma processing methodologies. The first, a "Plasma Processing Apparatus," aims to provide improved plasma processing uniformity. This innovative apparatus consists of a processing chamber, gas supply mechanisms, evacuation systems, and an electrode for placing objects to be processed, such as wafers. By introducing two distinct processing gases with varying compositions through separate inlets, this design controls the in-plane uniformity of critical dimensions while maintaining process depth uniformity.

The second patent, the "Plasma Processing Method," details a unique etching process for objects by generating plasma from a depositional gas within a processing chamber. By alternating between periods where the object is exposed to plasma and periods with lower etching rates, the technique ensures that the deposit film on the chamber’s inner walls becomes amorphous. This approach not only refines the etching process but also reduces particle generation stemming from increased processed sheets.
