发明名称 Method for improving the wet process chemical sequence
摘要 A method for semiconductor wafer etching clean-up comprising the steps of placing an oxide layer on a silicon wafer, cleaning the wafer surface with an etching agent cleaning solution, such as hydrofluoric acid, and washing the wafer surface with a cleaning solution, prior to an isopropanol vapor dry in order to reduce the number of defects caused by the formation of watermarks on the wafer surface.
