发明名称 Immersive oxidation and etching process for cleaning silicon electrodes
摘要 A process for cleaning a silicon electrode is provided where the silicon electrode is soaked in an agitated aqueous detergent solution and rinsed with water following removal from the aqueous detergent solution. The rinsed silicon electrode is then soaked in an agitated isopropyl alcohol (IPA) solution and rinsed. The silicon electrode is then subjected to an ultrasonic cleaning operation in water following removal from the IPA solution. Contaminants are then removed from the silicon electrode by soaking the silicon electrode in an agitated mixed acid solution comprising hydrofluoric acid, nitric acid, acetic acid, and water. The silicon electrode is subjected to an additional ultrasonic cleaning operation following removal from the mixed acid solution and is subsequently rinsed and dried. In other embodiments of the present disclosure, it is contemplated that the silicon electrode can be soaked in either the agitated aqueous detergent solution, the agitated isopropyl alcohol (IPA) solution, or both. Additional embodiments are contemplated, disclosed, and claimed.
