Claim:
1. A method for fabricating an electrowetting display, the method comprising: depositing a sacrificial photoresist layer on a support plate, wherein the support plate includes a substrate and an electrode layer, and wherein depositing the sacrificial photoresist layer at least partially covers the substrate and the electrode layer; placing a first mask on or over the sacrificial photoresist layer, wherein the first mask covers first portions of the sacrificial photoresist layer; exposing second portions of the sacrificial photoresist layer to electromagnetic energy; etching the second portions of the sacrificial photoresist layer so that the first portions of the sacrificial photoresist layer remain on the support plate; depositing a photoresist layer on the first portions of the sacrificial photoresist layer and the support plate; placing a second mask on or over the photoresist layer, wherein the second mask covers first portions of the photoresist layer; exposing second portions of the photoresist layer to electromagnetic energy; etching the second portions of the photoresist layer so that the first portions of the photoresist layer remain; and removing the first portions of the sacrificial photoresist layer to form liquid ducts between the support plate and the first portions of the photoresist layer.
