摘要： A microinjector uses bubbles as virtual valves to eject droplets of different sizes. The microinjector is in fluid communications with a reservoir and has a substrate, an orifice layer, and a plurality of nozzles. The substrate has a manifold for receiving ink from the reservoir. The orifice layer is positioned on the top of the substrate so that a plurality of chambers are formed between the orifice layer and the top of the substrate. Each of the nozzles has an orifice and at least three bubble generating components. The bubble generating components are selectively driven by a driving circuit so that each nozzle can eject droplets of different sizes.

摘要： A surface isolation device for isolating a predetermined area of a second surface of a wafer from an etching solution while the etching solution etches a first surface of the wafer to form a plurality of manifolds in the wafer. The surface isolation device has a base for positioning the wafer, a fixture for fixing the wafer on the base, and an isolation ring positioned on the base for isolating the predetermined area from the etching solution. When the fixture fixes the wafer on the base, the wafer sticks to the isolation ring, forming a seal that isolates the predetermined area from the etching solution.

摘要： A gradational etching method for high density wafer production. The gradational etching method acts on a substrate having a first passivation layer and a second passivation layer on a top surface and a bottom surface, respectively, of the substrate. A first etching process is performed to simultaneously etch the substrate and the first passivation layer to remove the first passivation layer. Finally, a second etching process is performed to etch the substrate to a designated depth that is used to control the thickness of the wafer after the second etching process.

摘要： An apparatus for using the bubble as a virtual valve to eject ink comprises a chamber, orifice, and heaters. The chamber, having a top surface and a bottom surface, is connected to the ink reservoir by a manifold. Two heaters, connected in series to a common electrode, are located on the bottom surface of the chamber. One heater having higher resistance is positioned adjacent to the manifold, and the other heater having lower resistance is positioned away from the manifold. When an electrical pulse is applied to activate the heaters, the heater close to the manifold heats up first, and generates a first bubble to isolate the ink flow between the chamber and manifold, thereby reducing the effects of cross talk. Subsequently, the heater away from the manifold generates the second bubble to pressurize the ink in the chamber with the first bubble, and the ink is ejected through the orifice. Then, the first bubble collapses, and breaks the isolation between the manifold and the chamber. The ink in the manifold immediately refills to the chamber.
