Abstract

A semiconductor processing device, comprising: a first chamber; a second chamber movable with respect to the first chamber portion between an open position and a closed position, a micro-chamber being formed between the first chamber portion and the second chamber portion when the second chamber portion is in the closed position with respect to the first chamber portion. The first chamber portion has a first channel formed on an inner wall surface of the first chamber portion facing the micro-chamber. The second chamber portion has a second channel formed on an inner wall surface of the second chamber portion facing the micro-chamber. When the second chamber portion is in the closed position with respect to the first chamber portion and a semiconductor wafer is accommodated in the micro-chamber, the first channel and the second channel communicate with each other and form an edge micro-processing space together, such that the outer edge of the semiconductor wafer accommodated in the micro-chamber extends into the edge micro-processing space. The edge micro-processing space is able to realize processing of the outer edge of the semiconductor wafer.
