Systems and methods for manipulating liquid films on semiconductor substrates |
摘要 |
A semiconductor substrate undergoing processing to fabricate integrated circuit devices thereon is spun about a rotational axis while introducing liquid onto a surface of the substrate. An annular-shaped sheet of liquid is formed on the surface, the sheet of liquid having an inner diameter defining a liquid-free void. The size of a diameter of the void is reduced by manipulation of the annular-shaped sheet of liquid. The void may then be enlarged until the surface is substantially dry. The annular-shaped sheet of liquid may be formed and altered by selectively moving a contact area on the surface of the substrate on which the liquid is introduced. Systems for processing a substrate and configured to deposit and manipulate a sheet of liquid thereon are also disclosed.
