Multi-layer monolithic fluid ejectors using piezoelectric actuation

A fluid ejector including a silicon wafer having a first side and a second side. A multi-layer monolithic structure is formed on the first side of the silicon wafer. The multi-layer monolithic structure includes a first structure layer formed on the first side of the silicon wafer, and the first str...

description	A fluid ejector including a silicon wafer having a first side and a second side. A multi-layer monolithic structure is formed on the first side of the silicon wafer. The multi-layer monolithic structure includes a first structure layer formed on the first side of the silicon wafer, and the first structure layer has an aperture. A second structure layer has a horizontal portion and closed, filled trenches or vertical sidewalls. The first structure layer, horizontal portion and the closed, filled trenches or vertical sidewalls of the second structure layer define a fluid cavity. An actuator is associated with the horizontal portion of the second structure layer, and an etched portion of the silicon wafer defines an open area which exposes the aperture in the first structure layer.
