Cleaning nozzle for advanced lithography process |
摘要 |
The present disclosure provides an apparatus for fabricating a semiconductor device. The apparatus includes a lithography tool. The lithography tool includes: a first nozzle configured to dispense a developer solution to a wafer; a second nozzle configured to dispense a cleaning solution to the first nozzle; and a controller configured to operate the second nozzle according to a predefined program. The present disclosure also provides a method of fabricating a semiconductor device. The method includes performing a developing process, wherein the performing the developing process includes dispensing a developer solution on a wafer using a first nozzle. The method also includes cleaning the first nozzle with a second nozzle, wherein the cleaning the first nozzle is executed according to one of a plurality of program recipes that each specify a sequence and a duration for which the first nozzle and the second nozzle are to be selectively activated. |
