20200070119 · 2020-03-05 ·

The present disclosure provides methods, device, and system for wafer processing. The wafer processing apparatus uses a nozzle in a lid to disperse a solution to the surface of a wafer. Further, the wafer is positioned on top of a vacuum chuck and does not spin while the solution is dispensed over the surface of the wafer via surface tension, thereby permitting the first solution to react with a reagent on the surface. Further, when dispensing the first solution, a separation gap between the lid and the wafer is at a predetermined distance, for example, from about 20 m to about 2 mm.
