摘要： A wafer dry cleaning method and apparatus capable of eliminating or suppressing adhesion of dust and particles on dried wafer surfaces while minimizing generation of water marks thereon. To achive this, the wafer dryer apparatus is configured including a surface cleaning/drying chamber structure which houses therein a set of spaced-apart silicon wafer workpieces. The dry chamber is operatively associated with a vacuum evacuation device for retaining the interior of this chamber at low pressures required. A water-drain device is provided for forcing water content separated off from the wafer surfaces to drain out of the drying vessel. During such wafer drying process, the wafers may be driven rotating at high speeds to thereby accelerate centrifugal spin-off of residual drops of water on wafer surfaces. Preferably, a chosen purge gas may be fed into the chamber during wafer rotation. The purge gas supply gets started substantially simultaneously upon activation of a vacuum pump for chamber evacuation, or after completion of such vacuum evacuation. In one illustrative embodiment ultrapure water may be used to rinse the wafers in the chamber.

摘要： 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.
