About
Tokyo Ohka Kogyo Co., Ltd. manufactures photoresists and high purity chemicals essential for semiconductor manufacturing. Their product range includes various types of photoresists compatible with different wavelengths of light, such as g-line, i-line, KrF, ArF, and EUV, which are used in photolithography processes. They also produce cleaning solutions, thinners, developers, and materials for advanced packaging processes, including bump photoresists and TSV photoresists. The company emphasizes high purity standards, with impurities in their products starting at less than 1ppm and reaching ppq for some items, supporting the miniaturization and performance of electronic components.
