    Abstract: In a particle-optical projection system (32) a pattern (B) is imaged onto a target (tp) by means of energetic electrically charged particles. The pattern is represented in a patterned beam (pb) of said charged particles emerging from the object plane through at least one cross-over (c); it is imaged into an image (S) with a given size and distortion. To compensate for the Z-deviation of the image (S) position from the actual positioning of the target (tp) (Z denotes an axial coordinate substantially parallel to the optical axis cx), without changing the size of the image (S), the system comprises a position detection means (ZD) for measuring the Z-position of several locations of the target (tp), a control means (33) for calculating modifications (cr) of selected lens parameters of the final particle-optical lens (L2) and controlling said lens parameters according to said modifications.

    Abstract: A high data-rate electron beam spot-grid array imaging system is provided that overcomes the low resolution and severe linearity requirements of prior art systems. Embodiments include an imaging system comprising an electron beam generator for simultaneously irradiating an array of spots spaced apart from each other on a surface of an object to be imaged, and a detector for collecting backscattered and/or secondary electrons emitted as a result of the interaction of the spots with the surface of the object to form an image of the irradiated portions of the object surface. A mechanical system moves the substrate in a direction which is nearly parallel to an axis of the array of spots such that as the substrate is moved across the spot array in the scan direction (the y-direction) the spots trace a path which leaves no gaps in the mechanical cross-scan direction (the x-direction). A compensator, such as a servo or a movable mirror, compensates for mechanical inaccuracies in the moving stage, thereby increasing imaging accuracy. In other embodiments, multiple detectors placed at different angles to the substrate collect electrons to provide multiple perspective imaging of the substrate surface.

    Abstract: An ion implantation method is disclosed in this invention. The disclosed method is for implanting a target wafer with ions extracted from an ion source traveling along an original ion beam path. The method includes steps of a) employing a set of deceleration electrodes disposed along the original ion beam path before the target wafer for decelerating and deflecting the ion beam to the target wafer; and b) employing a charged particle deflecting means disposed between the ion source and the set of deceleration electrodes for deflecting the ion beam away from original ion beam path and projecting to the set of electrodes with an incident angle for the set of electrodes to deflect the ion beam back to the original ion beam path for implanting the target wafer.

    Abstract: A charged particle beam exposure apparatus includes a charged particle beam generator, a deflector device for deflecting the charged particle beam electromagnetically to individually illuminate small areas of a pattern forming region formed on a transparent mask, apparatus for moving the transparent mask mechanically, and the various components required for reducing the charged particle beam pattern through the mask and projecting the same onto a semiconductor device substrate to be exposed. A semiconductor device is fabricated using such apparatus by moving the mask mechanically to position a pattern forming region at a predetermined exposure position. The pattern forming region includes a plurality of small areas which can be individually selected by deflecting the charged particle beam when the pattern forming region is positioned at the exposure position. Each individual area is of a size such that the entirety thereof is exposed when the beam is deflected onto such area.
