Latest Patents

Kazuyo Ijima holds a patent for a "Development defect preventing process and material." This invention involves a composition designed to reduce development defects in chemically amplified photoresist coatings. The composition includes an acidic component, such as a surfactant, which is applied to a photoresist coating on substrates with a diameter of 8 inches or more. By utilizing this process, the surface of the resist becomes hydrophilic, preventing the formation of a slightly soluble layer in the developer. This innovation results in an increased reduction in the thickness of the photoresist coating after development, enhancing the quality of resist patterns.
