The e-beam exposures presented here are written with 'SHOT A,10', i.e. a shot pitch of 5nm; this pitch works very well for large structures but not so well for 20nm or below. To illustrate this, ACHK screenshot are presented along with SEM inspection picures. | The e-beam exposures presented here are written with 'SHOT A,10', i.e. a shot pitch of 5nm; this pitch works very well for large structures but not so well for 20nm or below.
