Method For The Treatment Of A Semiconductor Wafer

Semiconductor wafers are treated in a liquid container filled at least partly with a solution containing hydrogen fluoride, such that surface oxide dissolves, are transported out of the solution along a transport direction and dried, and are then treated with an ozone-containing gas to oxidize the s...

Zusammenfassung:Semiconductor wafers are treated in a liquid container filled at least partly with a solution containing hydrogen fluoride, such that surface oxide dissolves, are transported out of the solution along a transport direction and dried, and are then treated with an ozone-containing gas to oxidize the surface of the semiconductor wafer, wherein part of the semiconductor wafer surface comes into contact with the ozone-containing gas while another part of the surface is still in contact with the solution, and wherein the solution and the ozone-containing gas are spatially separated such that they do not come into contact with one another.
