Abstract:
A method of microfabrication of an ultra-fine pattern in a target object, said method comprising:generating, at a beam source having at least two flat plate-type electrodes and capable of producing a large diameter beam, a large diameter fast atomic beam;positioning between said beam source and said target object a beam aperture control device including at least two shield plates having therein pin holes;passing said large diameter fast atomic beam from said beam source sequentially through said pin holes in said at least two shield plates and thereby producing an ultra-fine, linear fast atomic beam; andradiating said ultra-fine fast atomic beam onto a fabrication surface of said target object while subjecting said target object to at least one of rotation and a linear movement and thereby fabricating in said target object a pattern having a width of 0.1 to 100 .mu.m.
