Abstract: PURPOSE:To connect a first wiring to a second wiring without fail in a through hole by a method wherein an aluminum compound formed on the through hole inner wall during the through hole formation step is etched away later. CONSTITUTION:During the formation step of a thorough hole 23, an interlayer insulating film 13 is overetched away so as not to be left on the bottom surface of the through hole 23.

Abstract: PURPOSE:To eliminate time loss associated with the movement of a sample by electrically deflecting a charged corpuscular beam follow the mechanical movement of the sample in a high speed and wide range mapping apparatus requiring a sample moving mechanism. CONSTITUTION:An electron beam emitted from an electron gun 14 and forcused with an electron lens 16 is radiated at a point n11 of a sample 6 fixed on an XY stage 5.

In this manner, as soon as the measurement is completed upto the point n1i, the deflection is shifted to the starting point 11. The gain of a beam scan power source 8b is adjusted so that the movement of the irradiation position of the electron beam due to the deflection equals the movement of the stage 5 with a stage controller 2 and the electron beam is moved following the stage 5 thereby eliminating loss of the sample moving time.
