Method for modifying resist images by electron beam exposure

It has now been surprisingly found that by exposing a photoresist to flood electron beam exposure in combination with optical exposure, that the pullback on the upper region of lithographic images in resist can be virtually eliminated during electron beam processing. This unexpected result is due to the fact that the electron beam exposure and optional bake are carried out prior to development of the resist. This means that the resist shrinkage that is seen as a result of these steps is constrained laterally by the resist film itself. Thus, the resist is free to shrink vertically, and the resulting shrinkage provides a reduction in the line slimming and an improvement in the etch rate of the resist. This leads to the formation of a better resist image.

Method of electron beam processing

As a rule, electron beam welding takes place in a vacuum. However, this means that the workpieces in question have to be placed in a vacuum chamber and have to be removed therefrom after welding. This is time-consuming and a serious limitation of a process the greatest advantage of which is the option of welding workpieces of large thicknesses. Therefore the idea is to guide the electron beam (2) to the workpiece via a hollow wire, said wire thereby acting as a prolongation of the vacuum chamber (4) down to workpiece. Thus, a workpiece need not be placed inside the vacuum chamber, thereby exploiting the potential of electron beam processing to a greater degree than previously possible, for example by means of electron beam welding.
