Abstract: In the production of semiconductors it is necessary to inspect circuit patterns on wafers. In circuits having very small details (for example, 40 nm), inspection can be carried out by means of electron beam columns, a plurality of wafers then being inspected at the same time and the signals being compared on-line. In an inspection apparatus in accordance with the invention more beam columns 1 to 7 are provided for every wafer A, B, C in order to obtain a high feed-through rate. The inspection is carried out by way of an x-y scan and the wafers are fed through according to a rectilinear movement, thus providing the possibility of scanning only the Care Area Fraction of the wafers, resulting in a high feed-through rate for the wafers in the inspection apparatus.

Abstract: The invention relates to wafer inspection by means of a scanning electron microscope (SEM) column in which the secondary electron detector 22, 24 is positioned centrally above the objective lens of the column. Secondary electrons that leave the central part of the specimen in a direction substantially perpendicular to its surface are inevitably collected in the central part of the detector surface where the bore 36 for the primary beam 6 is situated. Consequently, such electrons do not contribute to the detector signal. In order to avoid such a detrimental loss of signal contribution, it is proposed to provide a central electrode 35 in the central bore 36 such that secondary electrons that approach the bore are driven aside towards the electron-sensitive detector region 48.

A preferred embodiment is provided with an additional (condenser) lens 24 such that the object distance remains constant when the magnification of the lens system 18, 24 is varied.
