Abstract:
A method for producing templates for microfabrication, comprising the steps of:forcing a first liquid through a channel of a feeding source in a manner which causes the liquid to be expelled from an exit opening;forcing a second liquid immiscible with the first liquid through a pressure chamber in a manner which causes the second liquid to exit the pressure chamber from an exit orifice downstream of a flow path of the first liquid expelled from the exit opening of the feeding source;wherein a stable first liquid-second liquid interface is maintained and the first liquid forms a stable capillary jet focused to smaller dimensions on the exit orifice of the pressure chamber by the second liquid.
