High Resolution Positive Photoresist For Submicron Photolithography

Hidekatsu Kohara; Hatsuyuki Tanaka; Masanori Miyabe; Yoshiaki Arai; Shingo Asaumi; Toshimasa Nakayama

Optical lithography is achieving itself into submicron region. In the limitation of resolution for stepper there is a decrease in contrast and so it requires more exposure amount than that of D. Also it is not possible to achieve faithful transcription of fine pattern dimension. The resolution of TSMR-8800 which is developed as high resolution positive photoresist is 0.6 μm. Faithful transcription of the mask pattern is possible for 0.7 μm line and space pattern. It shows good properties compared with conventional photoresist.
