A method and mobile device for performing wireless channel selection that employs more than one concurrent level 2 interface to facilitate a level 3 handoff. The apparatus may receive an indication of traffic to be routed through a multiple stage switch network configured to route the traffic from one or more input ports to one or more output ports according to a type of the traffic. Firstly, the silicon area outside the gate is converted to oxide while protecting a silicon ledge adjacent to the gate with a first spacer. The planar coil spring applies a torque to the wind-up link to rotate the wind-up link about the spring axis to assist movement of the support member from the closed position into the open position. A chamber layer and a nozzle layer are formed on the substrate, wherein the nozzle layer has a nozzle corresponding to the energy generating elements, and at least one of the chamber layer and the nozzle layer is formed using a photocurable resin composition that includes a photo-base generator, an epoxy resin and a non-photoreactive solvent. A channel is arranged on the buffer layer or on the substrate, and a capping layer is arranged on the channel.
