Latest Patents

Satoshi Shikami holds 1 patent related to the recycling of waste sulfuric acid. This patent describes a method where sulfuric acid, used in the fabrication of semiconductor devices, can be recycled to minimize the amount discarded. The process involves feeding sulfuric acid effluent into an anode chamber of a sulfuric acid-concentrating electrolyzer, which is partitioned by at least one cation exchange membrane. This setup concentrates the sulfuric acid and generates oxidizing substances, allowing the acid to be reused in the manufacturing process. When impurities accumulate beyond a certain threshold, a portion of the sulfuric acid is sent to a refining unit, where it is purified and returned to the system. This innovative recycling method produces sulfuric acid with high oxidizing power without the need for additional oxidizing agents like hydrogen peroxide.
