Title: Film surface treatment method and film surface treatment device
Inventor: DENG ZHIGUO
IPC: H01L21/677
Filed: 2019-12-25
Abstract: A film surface treatment method and a film surface treatment device, substances on a film surface can be etched away by using hydrofluoric acid to etch the film surface. Residual hydrofluoric acid on the film surface is removed by using a cleaning solution to clean hydrofluoric acid on the film surface after the etching treatment, which can avoid excessive etching of the film caused by the residual hydrofluoric acid. Thus, a dense and uniform oxide layer can be formed on the film surface by using ozone water to oxidize the film surface after the cleaning treatment. Therefore, the ELA process effect can be improved while performing the ELA process.
