发明名称 Semiconductor IC device fabricating method
摘要 Either a chemical amplification positive electron beam resist film or a chemical amplification negative electron beam resist film is used selectively according to an IC fabricating process when forming a minute IC pattern by using, as a mask, a resist pattern formed by irradiating the chemical amplification electron beam resist film formed on a semiconductor wafer with an electron beam, to form the minute IC pattern quickly in a high accuracy and to carry out an electron beam direct writing at a high throughput. The chemical amplification electron beam resist film is coated with a conductive polymer film before irradiating the same with the electron beam to prevent the charging-up of the chemical amplification electron beam resist film and to stabilize the chemical amplification electron beam resist film during a electron beam writing process.
