Abstract:
A semiconductor processing apparatus is provided. The apparatus includes a first chamber portion and a second chamber portion movable relative to the first chamber portion between an open position and a closed position. The first chamber portion includes a recessed area formed on an internal surface of the first chamber portion. The first chamber portion also includes one or more through-holes connected to respective locations of the recessed area. When the second chamber portion is in the closed position and a semiconductor wafer is housed in the micro chamber, the recessed area is sealed by a surface of the semiconductor wafer to form a closed channel. The surface may be processed by a processing fluid flowing in the closed channel. Accordingly, a flowing direction and a flowing speed of the processing fluid may be accurately controlled, and an amount of the processing fluid consumed may be greatly reduced.

Claim (Index 12):
The semiconductor processing apparatus according to  claim 11 , wherein:\n the integral recess has a circular shape, the low region is located in a central region of the integral recess and the high region is located in a peripheral region of the integral recess, or the high region is located in the central region of the integral recess and the low region is located in the peripheral region of the integral recess, the first or second through-hole connected to the peripheral region of the integral recess comprises a plurality of through-holes, and a radial line extending from the central region toward the peripheral region along the bottom surface of the integral recess is an oblique straight line or an oblique curve line.
