Abstract: PURPOSE:To permit in-line inspection process after dry etching by a method wherein an electron beam is irradiated on the processed surface and both resultant secondary electron beam image and characteristic X-ray image are used to inspect a pattern. CONSTITUTION:An Si substrate is placed in a connector 4 held under vacuum similar to an etching chamber 1, and the surface including a pattern is scanned by a minute spot-like electron beam emitted from an inspection unit 5.
