摘要:
A to-be-polished surface of a semiconductor workpiece is polished to a target shape, using a CMP tool. The to-be-polished surface is a surface of a metal provided on an insulating film having trenches. A shape of a polished surface of the semiconductor workpiece is monitored to determine if a metal residue exists outside of the trenches on the polished surface while the semiconductor workpiece is set in the CMP tool, using a monitor. The monitor has a sensor that obtains a two-dimensional image of the to-be-polished surface. The CMP tool is controlled by feedback based on a result of monitoring to determine if the metal residue exists, using a controller.

The purpose of the present invention is to avoid a decrease in the mechanical strength of a Si substrate because of the repetition of ion-implantation and annealing processes. As ions are implanted while the Si substrate surface temperature is kept at as low as −60° C. or less. Then the Si substrate is heated to recover the implantation defects caused by the ion-implantation. Such a combination of the low temperature ion-implantation and the annealing processes is repeated as required.

An electron beam lithography system 10 comprises an electron gun including a rectangular cathode 1 having an emission surface having an aspect ratio of other than 1, an illumination optical system 3 of an asymmetric lens system including multipole lenses Qa1 and Qa2, a CP aperture 5, and a projection optical system 8 of a symmetric lens system including multipole lenses Qb1 through Qb4. This electron beam lithography system 10 is used for emitting an electron beam at a low acceleration of 5 kV or less from the rectangular cathode 1, for controlling the illumination optical system so as to form an image of a desired character of the CP aperture 5 on an isotropic plane of incidence at different demagnifications in minor-axis and major-axis directions in accordance with the aspect ratio of the rectangular cathode 1, and for controlling the projection optical system 8 so that the electron beam leaving the CP aperture 5 as an aperture image is incident on a substrate 21 at the same demagnification in the minor-axis and major-axis directions and at different incident angles in the minor-axis and major-axis directions while passing through the trajectory without establishing any crossovers.

An equipment for manufacturing semiconductor devices, comprises a processing tool which processes a to-be-processed surface of a semiconductor workpiece to a target shape, a monitor which three-dimensionally monitors a shape of a processed surface of the semiconductor workpiece while the semiconductor workpiece is set in the processing tool, and a controller which controls the processing tool in a feedback manner on the basis of the shape of the processed surface monitored by the monitor. If the shape of the processed surface deviates from the target shape, the controller adjusts process conditions of the processing tool so that the target shape can be obtained.
