Fabrication of a high-resolution mask by using variable-shaped electron beam lithography with a non-chemically amplified resist and a post-exposure bake
Photomasks have been fabricated by VSB 50keV EBL. Examine PEB temperature dependence of CD error. Resist sensitivity by changing PEB temperature has been verified. Demonstrate the use of PEB with non-CAR resist helps suppress proximity effect and high resolution technique.
