Use of mixed bases to enhance patterned resist profiles on chrome or sensitive substrates
摘要:
Resist compositions having good footing properties even on difficult substrates are obtained by using a combination of base additives including a room temperature solid base, and a liquid low vapor pressure base. The compositions are especially useful on metal substrates such as chromium-containing layers commonly used in mask-making.
