dc.description.abstract | We present a simple strategy to reduce the writing time of electron beam lithography (EBL) by using a highly sensitive Shipley's UV-5 resist while reducing proximity effects by depositing a thin film of silicon dioxide (SiO2) on silicon substrate. It was found that a simple insertion of a thin SiO2 film greatly reduced proximity effects, thereby providing enhanced resolution and better pattern fidelity. To support this conclusion, the bottom line width and sidewall slope of the developed pattern were analyzed for each substrate with different film thickness. | en |
