Abstract

The demand for tools suitable for deposition of small amount of material is continuously increasing. A standard SiN cantilever was modified in order to dispense single droplets of femto- and ato-liter (NAnoscale DISpensing (NADIS)). In order to open a nano fluid channel, holes down to 100 nm were milled in the apex of the cantilever using FIB. The liquid to dispense is loaded on the top-side of the cantilever extremity.
