Title: Electron beam exposure system
Inventor: SUEHIRO MASAYUKI
IPC: H01L21/027
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To improve the area efficiency of an electron beam exposure system by exposing a substrate to be exposed along its cleavage plane by incorporating an electron channeling observing device in the exposure system and scanning the object to be exposed with an electron beam, based on the observed result of the electron channeling pattern of the object. SOLUTION: An electron beam exposure system is different from the variable square electron beam lithography system available on the market in the program of a signal processing processor 2, which observes the surface of a substrate 1 by detecting electrons reflected from the substrate 1. Namely, a program 3 for observing electron channel pattern is incorporated in the function of the processor 2 to observe the electron channeling pattern of the substrate 1 to be observed. In this case, in addition, the observed part of the substrate 1 is worked so that the surface of the substrate 1 may be exposed.  When the exposure system is constituted in such a way, elements can be arranged with a high density without breaking the elements, because the substrate 1 mounted on a stage is adjusted so that the substrate may be scanned with an electron beam in the observed direction of cleavage of the substrate, even when the direction of cleavage is deflected more or less.

Title: Contour forming method
Inventor: FUKUI TAKAHARU
IPC: G06T7/60
Filed: 1993-05-25
Abstract: PURPOSE:To form a contour that has the features of an original contour and does not include any fine recessed/projecting part consisting of the contour dots despite the magnification of a graphic by applying the interpolation among the contour dots forming an apex at a corner part of the original contour by means of a straight line or a curve for formation of the contour. CONSTITUTION:The contour dots of a graphic are extracted from the bit map data stored in a memory 18, and these contour dot data are stored in a memory 20. Then the contour dot showing the features of an original contour is extracted from those contour dots stored in the memory 20 as a key point of the original contour. Then the pattern of the contour dot extracted as a key point is analyzed, and the key point positioning at the apex of a corner part formed by the original contour is detected. Then the interpolation is applied among the contour dots which form an apex of the corner part, and a cutting plotter forms the contours to be cut. Thus it is possible to form a smooth contour that has features of the corner part, etc., of the original contour and does not include any conspicuous and fine recessed/projecting part consisting of the contour dots.
