Patent number: 5677113Abstract: The object of the invention is to provide an ashing method and an asher in order to avoid damage to semiconductor components occurring during ashing of a photoresist resin film by active oxygen plasma and to avoid a long treatment time occurring in an ashing method using a low pressure mercury discharge lamp. According to the invention, this object is achieved by a method and an apparatus for ashing a photoresist resin film. In the method, a wafer provided with a photoresist resin film is placed in an ozone-containing atmosphere. An activated oxygen is produced through the radiation light of a discharge lamp, which emits a continuous spectrum in a wavelength range of 200 to 300 nm. The photoresist resin film is ashed by the activated oxygen.Type: GrantFiled: May 8, 1995Date of Patent: October 14, 1997Assignee: Ushiodenki Kabushiki KaishaInventors: Shinji Suzuki, Kyohei Seki, Nobutoshi Ebashi, Tetsuji Arai
