Pd. Cui Z",p,"prewett et S. Johnson, TRANSMISSION AND SIDE-LOBE EFFECT IN ATTENUATED PHASE-SHIFT MASKS, Microelectronic engineering, 27(1-4), 1995, pp. 259-262
The performance of attenuated PSMs was characterised by light transmis
sion and side-lobe effects for dense contacts, isolated contacts, line
/space arrays and isolated lines. Log-intensity slope and depth of foc
us for these features were compared at transmission up to 15%. The pri
ntability of side-lobes was analysed and compared with i-line printed
resist images.
