Latest Patents

Rong-Jer Lee holds a patent for a process titled "Process for etching organic polymeric materials." This invention describes a wet etching process designed for forming vias or pre-designed patterns in organic polymeric layers, such as fully or substantially fully cured polyimide layers. The process involves placing the organic polymeric layer in an etching bath containing two electrodes immersed in an etching solution. An alternating current with a voltage of about 0.3 to 1.0 volt and a frequency of about 60 Hz, or a direct current of about 0.8 to 20 volts, is applied to the electrodes. The etching solution contains acid or metallic hydroxide and optionally includes 3-15 wt % N-methyl-2-pyrrolidone. This invention provides a fast and safe etching technique, eliminating the need for toxic and explosive chemicals such as hydrazine hydrate or ethylene diamine.
