Title: Method and apparatus for projection exposure of line pattern
Inventor: TAMECHIKA EMI
IPC: G03F7/20
Filed: 1991-08-23
Abstract: PURPOSE:To set the degree of expansion and inclination of an incident light flux to correspond to a pattern for forming an excellent fine pattern by making an aperture diaphragm of a secondary light source emission part of projection exposure removable or by allowing the aperture diaphragm to have an aperture area adjusting function. CONSTITUTION:Between a first projection lens 13 and a second projection lens 14, a projection aperture diaphragm 15 is located. Light which is diffracted by a mask pattern of a reticle 12 forms an image on the surface of a wafer 16 through the projection lens system. A condensing lens system 11 having a zooming function is installed and is so adjusted that a light source may be located on a minus-side focal plane of this lens system at all times. When a magnification, namely, a focal distance, of the condensing lens 11 is changed, a high resolution can be stably obtained in the pattern formation of an LSI, etc., wherein a focal position is not changed in each of the cases when an inclination of oblique incidence is small (a) and when it is large (b). Consequently, the degree of integration and a reliability can be increased.
