Systems and methods for treating substrates with cryogenic fluid mixtures

Disclosed herein are systems and methods for treating the surface of a microelectronic substrate, using a cryogenic fluid mixture used to treat an exposed surface of the microelectronic substrate. The fluid mixture may be expanded through a nozzle to form an aerosol spray or gas cluster jet (GCJ) spray may impinge the microelectronic substrate and remove particles from the microelectronic substrate's surface. The fluid mixture may include nitrogen, argon, helium, neon, xenon, krypton, carbon dioxide, or any combination thereof. The incoming fluid mixture may be maintained pressure greater than atmospheric pressure and at a temperature greater than the condensation temperature of the fluid mixture. The fluid mixture may be expanded into the treatment chamber to form an aerosol or gas cluster spray. In this embodiment, the nozzle may be positioned within 50 mm of the microelectronic substrate during the treatment, more preferably within 10 mm of the microelectronic substrate.

Apparatus and method of treating surface of semiconductor substrate

In one embodiment, an apparatus of treating a surface of a semiconductor substrate comprises a substrate holding and rotating unit, first to fourth supplying units, and a removing unit. A substrate holding and rotating unit holds a semiconductor substrate, having a convex pattern formed on its surface, and rotates the semiconductor substrate. A first supplying unit supplies a chemical onto the surface of the semiconductor substrate in order to clean the semiconductor substrate. A second supplying unit supplies pure water to the surface of the semiconductor substrate in order to rinse the semiconductor substrate. A third supplying unit supplies a water repellent agent to the surface of the semiconductor substrate in order to form a water repellent protective film onto the surface of the convex pattern. A fourth supplying unit supplies alcohol, which is diluted with pure water, or acid water to the surface of the semiconductor substrate in order to rinse the semiconductor substrate. A removing unit removes the water repellent protective film with the convex pattern being left.

Substrate treatment system, substrate transfer method and computer storage medium

An interface station of a coating and developing treatment system has: a cleaning unit cleaning at least a rear surface of a wafer before the wafer is transferred into an exposure apparatus; an inspection unit inspecting the rear surface of the cleaned wafer whether the wafer is exposable, before it is transferred into the exposure apparatus; wafer transfer mechanisms including arms transferring the wafer between the units and a wafer transfer control part controlling operations of the wafer transfer mechanisms. When it is determined that a state of the wafer becomes an exposable state by re-cleaning in the cleaning unit as a result of the inspection, the wafer transfer control part controls the wafer transfer mechanisms to transfer the wafer again to the cleaning unit.
