Methods are provided for producing a pristine hydrogen-terminated silicon
wafer surface with high stability against oxidation. The silicon wafer is
treated with high purity, heated dilute hydrofluoric acid with anionic
surfactant, rinsed in-situ with ultrapure water at room temperature, and
dried. Alternatively, the silicon wafer is treated with dilute
hydrofluoric acid, rinsed with hydrogen gasified water, and dried. The
silicon wafer produced by the method is stable in a normal clean room
environment for greater than 3 days and has been demonstrated to last
without significant oxide regrowth for greater than 8 days.
