Abstract:
1. A planar device for ion control in a low pressure environment comprising: a substantially planar substrate; a conductive layer formed on the planar substrate; an orifice passing through the conductive layer and the planar substrate for receiving ions; a structure for generating an electric field, said structure formed in the conductive layer in an area surrounding the orifice such that when a voltage is applied to the structure the electric field is generated that extends above a top surface of the structure that either funnels ions in a space above the top surface towards and through the orifice or disperses the ions that pass through the orifice as the ions move away from the top surface; and connectors configured to receive power for supplying a voltage to the structure to generate the electric field, wherein an entirety of the planar device lies substantially within a single plane.
