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 15):
A semiconductor processing method using a semiconductor processing apparatus,\n the semiconductor processing apparatus comprising:\n a first chamber portion; and \n a second chamber portion movable relative to the first chamber portion between an open position and a closed position, \n 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 groove formed on an internal surface of the first chamber portion, the internal surface facing the micro chamber; and \n a first through-hole passing through the first chamber portion from an outer side of the first chamber portion and connected to the recessed groove, \n a second through-hole passing through the first chamber portion from the outer side of the first chamber portion and connected to the recessed groove, and \n \n 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 a closed channel is formed by the surface of the semiconductor wafer and the recessed groove, the closed channel connected to the outer side of the first chamber portion via the first and second through-holes; \n \n the method comprising:\n positioning the second chamber portion in the open position relative to the first chamber portion; \n placing the semiconductor wafer between the first and second chamber portions; \n positioning the second chamber portion in the closed position relative to the first chamber portion; \n injecting an extraction fluid into the recessed groove via the first through-hole such that the extraction fluid proceeds along the closed channel and reaches the second through-hole; and \n extracting the extraction fluid via the second through-hole.
