    Abstract: A method of manufacturing a fluid injection device. The method of the present invention applies a compensated geometric shape of the unetched isolating portions to increase the additional compensated portion for etching, or the ion implanting process to reduce the etching rate of the unetched isolating portions. Thus, crosstalk or overshoot in the isolating portions of the fluid injection device can be reduced, and the fluid injection device can be precisely manufactured in a small size.

    Abstract: The present disclosure pertains to our discovery of a particularly efficient method for etching a multi-part cavity in a substrate. The method provides for first etching a shaped opening, depositing a protective layer over at least a portion of the inner surface of the shaped opening, and then etching a shaped cavity directly beneath and in continuous communication with the shaped opening. The protective layer protects the etch profile of the shaped opening during etching of the shaped cavity, so that the shaped opening and the shaped cavity can be etched to have different shapes, if desired. In particular embodiments of the method of the invention, lateral etch barrier layers and/or implanted etch stops are also used to direct the etching process. The method of the invention can be applied to any application where it is necessary or desirable to provide a shaped opening and an underlying shaped cavity having varying shapes. The method is also useful whenever it is necessary to maintain tight control over the dimensions of the shaped opening.

    Abstract: The present invention relates to a method of manufacturing microstructure by the anisotropic etching and bonding of substrates so as to manufacture mechanically functioning micro-structures in various forms by uniting the same or different substrate bonding technique and selective anisotropic etching technique. This invention manufactures a pyramidal optical divider or an optical divider with a pyramidal structure located on a quadrilateral pillar by bonding one substrate on a substrate different in the direction of crystallization and anisotropically etching them thereafter. This invention manufactures variously shaped nozzles by bonding those substrates crystallized in a different direction and anisotropically etching them so that substrates bonded by one photograph transferring process may form different etching holes. This invention manufactures a diaphragm having a uniform thickness and a wide area by bonding two substrates different in the direction of crystallization or in the concentration of an impurity, removing a substrate of prescribed concentration and anisotropically etching only one substrate of the remaining substrates.

    Abstract: Disclosed is a method of fabricating a precision etched, three dimensional device from a silicon wafer, wherein the etching is done from one side of the wafer using a two step silicon etching process. A two-sided deposition of a robust protective layer, such as polycrystalline silicon, is placed over a two-sided deposition of a chemical masking layer such as silicon dioxide. The two layers are concurrently patterned with first and second sets of vias on one side of the wafer, while the opposite side is protected by the protective layer. The protective layer is removed to permit deposition of a second masking layer such as silicon nitride, followed by deposition of a second protective layer. Again, the second protective layer prevents damage to the fragile second masking layer on the wafer backside while its frontside is patterned with a similar set of vias aligned with the first set of vias in the first masking layer. This similar set of vias is sequentially formed in both the second protective layer and the underlying second masking layers. Then the wafer is placed in an etchant bath so that the first set of recesses is anisotropically etched in the wafer frontside side. Next, the second protective layer and second masking layer are removed to permit anisotropic etching of the second set of recesses through the second set of vias in the first masking layer. If the protective layer is polycrystalline silicon, it is concurrently etch-removed during the initial etching of the silicon wafer.
