Patent ID: 7052616

Claim:
A method for producing a fluidic device, the method comprising: patterning a first structural material on a substrate; removing regions of said first structural material to produce a first patterned structural layer; depositing first sacrificial material onto regions of said substrate where first structural material has been removed, producing a first sacrificial layer; patterning; depositing electrode material onto the surface of first structural material of said first patterned structural layer to produce a first electrode; patterning; depositing second sacrificial material to produce a second sacrificial layer on said first electrode and regions of said first sacrificial layer on said first patterned structural layer; depositing cap of channel material to produce a channel cap layer; depositing capping material onto said channel cap layer to produce a capping layer; removing said first sacrificial layer and said second sacrificial layer to produce a device having a gap region resulting from the removal of the portion of said second sacrificial layer between said cap of channel material and said first electrode and a fluid control channel continuous with said gap region resulting from the removal of the remaining portion of said second sacrificial layer and said first sacrificial layer.
