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 1):
A semiconductor processing apparatus, comprising:\n a first chamber portion; and a second chamber portion movable relative to the first chamber portion between an open position and a closed position, wherein:\n when the second chamber portion is in the closed position relative to the first chamber portion, a micro chamber is formed between the first chamber portion and the second chamber portion, the micro chamber configured to house a semiconductor wafer, \n when the second chamber portion is in the open position relative to the first chamber portion, the micro chamber is configured for the semiconductor wafer to be transferred into or out of the micro chamber, \n the first chamber portion comprises:\n a recessed area formed on an internal surface of the first chamber portion, the internal surface facing the micro chamber; and \n either or both of a first through-hole and a second through-hole, the first through-hole passing through the first chamber portion from an outer side of the first chamber portion and connected to a first location of the recessed area, the second through-hole passing through the first chamber portion from the outer side of the first chamber portion and connected to a second location of the recessed area, and when the second chamber portion is in the closed position relative to the first chamber portion and the semiconductor wafer is housed in the micro chamber, a surface of the semiconductor wafer abuts against the internal surface such that the recessed area is sealed by the surface of the semiconductor wafer to form a closed processing space between the surface of the semiconductor wafer and the first chamber portion, the closed processing space connected to the outer side of the first chamber portion via the first through-hole, the second through-hole, or both.
