Inorganic resists such as amorphous alumina are projected as potential candidates for high resolution electron beam nanolithography, with drawbacks on low sensitivity and tedious deposition process such as sputtering. Therefore, a spin-coatable Al2O3 resist with higher sensitivity is strongly desirable to overcome these drawbacks. The electron beam exposure characteristics of spin-coatable Al2O3 gel films prepared by aluminum tri-secbutoxide, Al(OBus)3, with chelating agents like ethylacetoacetate (EAcAc) are investigated.
