Abstract
Maskless electron beam lithography is an attractive solution to address sub-90 nm technology nodes with high throughput and manufacturing costs reduction. One of the key challenges is to meet entirely process/integration specifications in terms of resolution, resist sensitivity, roughness and etch transfer into underlayers. In this paper, we evaluate and identify the optimal stack to fit printing performance using e-beam exposures and etch transfer patterning. Besides imaging performance, other key parameters such as outgassing and charge dissipation due to high current density are also considered to fully achieve targets for the machine developed by MAPPER Lithography.
