Publication number: 20240076547Abstract: It is known that when etching gold films using etching solutions containing iodine and iodide, N-methyl-2-pyrrolidinone (NP) is added to improve the etching solution's wettability, microfabrication property, and solution life. However, in recent years, the use of NMP has been regulated due to its adverse effects on human health. The present invention provides an etching solution and etching method for gold film that improves wettability, microfabrication property, and solution life without containing NP. In order to address the problem of the prior art, the present invention provides etching solutions and etching methods for gold films that improve wettability, microfabrication property, and liquid life without NMP, characterized by the inclusion of a specific organic solvent in the etching solution containing iodine and iodide.Type: ApplicationFiled: January 19, 2022Publication date: March 7, 2024Applicant: KANTO KAGAKU KABUSHIKI KAISHAInventors: Itsuki KASHIWAGI, Yuki YOSHIDA, Koichi INOUE, Iori KAWASHIMA
