Paper Abstract

The multi-component, positive acting, chemically amplified deep-UV ((lambda) equals 248 nm) resist ARCH, has been evaluated for use in proximity x-ray and electron-beam lithography. Characterization of the x-ray lithographic response of ARCH resist using a pulsed laser point source ((lambda) equals 1.4 nm) proximity print stepper resulted in a process producing sub-0.20 micrometers features at a dose of 22 mJ/cm2. A time delay study was conducted in the helium environment of the x-ray exposure tool and the results indicate that a > 30 min delay period after exposure produced no change in the resist image profile. Electron- beam exposures using a JEOL JBX 5D-II tool operating at 50 KeV delineated patterns below 0.10 micrometers on silicon. The measured exposure sensitivity was in the range of 8-16 (mu) C/cm2. Time delay experiments performed in the vacuum environment of the e-beam exposure tool over a 15 hr. time period resulted in no line size variation. These results suggest that ARCH resist represents a common material platform for the various advanced lithography programs currently under investigation for fabrication of circuits having
