TTWI762175B Self-Healing Resin Composition and Use Thereof:
The patent relates to the composition and application of a self-healing resin that exhibits excellent heat resistance and/or weather resistance.
TWI779994B Purification Method of Iminodiacetic Acid:
The patent relates to a purification method for iminodiacetic acid, specifically a simple purification technique that effectively reduces the metal content in iminodiacetic acid.
  • The product is primarily used for cleaning wafers after the etching process, specifically for surface cleaning after copper etching processes.
  • By controlling the crystallization temperature curve during the purification of the raw material, consistent crystal structure can be obtained. Through secondary crystallization, the concentration of metal ions in the raw material can be reduced from the ppm level to the ppb level.
