Abstract:
The invention provides a method of burying trenches of a sample comprises at least the steps of: from the sample having the trenches extending from one surface into a depth direction, cutting a sample piece of a small part including the trenches; and by irradiating an electron beam toward the inside of the trenches from a side surface extending along the depth direction of the sample piece and simultaneously injecting a compound gas into the inside of the trenches from openings on the side of the one surface of the trench, decomposing the compound gas with secondary electrons generated by irradiation of the electron beam and depositing constituents of the compound gas within the trenches. Therefore, the method can bury the trenches uniformly without generating cavities within the trenches even if the trenches of the sample piece have a high aspect ratio deep in a depth direction.

Claim (Index 2):
The method of burying trenches of a sample according to  claim 1 ,\n wherein in said depositing step, the constituents of the compound gas are sequentially deposited toward the openings from the bottom of the trenches by scanning the electron beam toward the openings from the bottom of the trenches.
