Abstract:
A substrate cleaning apparatus which comprises:a substrate holder for holding a substrate; a high-pressure cleaning liquid jetting mechanism having a sponge with a solid portion and a hollow portion, and a high-pressure nozzle mounted within the hollow portion of the sponge, wherein said solid portion contacts one planer surface of said substrate held by said substrate holder and said nozzle jets the cleaning liquid in the hollow portion at said one planer surface to form cavities of the cleansing liquid on the planer surface of the semiconductor substrate, wherein breakage of the cavities generates high frequency sonic waves including frequency components continuous in a band of several hundred kHz and not more than 1 MHz; a chamber housing said substrate holder and said high-pressure cleaning liquid jetting mechanism; a gas-feeding port communicated with said chamber; a gas exhaust port communicated with said chamber; and a rinsing water feeding pipe for feeding a rinse liquid to the other planer surface of said substrate.
