Paper Abstract

This paper presents the fabrication and assembly techniques for high resolution lens assemblies such as the projection lenses used for submicron photolithography. In order to meet the stringent precision and dimensional stability requirements for such lens assemblies the aluminum lens cells are machined and heat treated in several steps to achieve the required accuracies. Special optical tools and mechanical gages are then used to assemble the lenses into the cells on an airbearing table. 1.
