Abstract
Abstract An apparatus for treating solid surface using a thermally excited molecular beam according to the present invention is capable of completely preventing flying of contaminant caused by a heating source to a sample. To achieve this, in the present invention, the heating source for exciting the molecules is hermetically separated from the sample. Alternatively, a container where the heating source is housed and a container where the sample is accommodated are separated such that a conductance between the two containers is sufficiently small. In this way, chemical reactions between the molecular beam of the reactive gas which is highly reactive and the heating source heated to high temperatures can be eliminated, and flying of the contaminant to the sample can thus be greatly reduced. As a result, flying of the contaminating substances caused by the heating source to the sample can be prevented, and reduction in the surface treating rate of the sample, caused by the contaminant, can be prevented.
