Abstract
Preliminary evaluation of a 1:1 proximity x-ray stepper, built by Hampshire Instruments is discussed here. This stepper, model 5000P, is the first commercial system that uses a laser- generated plasma x-ray source. It was extensively tested at the supplier's facility and in July 1991 it was shipped to AT&T Bell Labs, where its installation is nearly completed.
