Geometry of nanopore devices fabricated by electron beam lithography: Simulations and experimental comparisons
Geometry of solid-state nanopores was calculated from electron energy distributions in EBL. We investigated the effects of dose, operating blur, substrate, and dosing pattern. Higher beam blur and lower dose cause greater pore tapering in sub-10nm pores. Blur and dose can be chosen for a target tapering angle and pore size at a given depth. Secondary electrons are responsible for tapering and beam broadening in the resist.
