    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: In a method for producing a diaphragm sensor array having a semiconductor material substrate on which a plurality of planar diaphragm regions is arranged as a carrier layer for sensor elements, the planar diaphragm regions are thermally decoupled from one another by crosspieces made of a material having clearly better heat conductive properties compared to the diaphragm regions and the lateral surroundings of the crosspieces. Masking for a subsequent step for producing porous semiconductor material is applied at the locations of the semiconductor material substrate at which the crosspieces for the thermal decoupling are formed, and the semiconductor regions not protected by the masking are rendered porous and the diaphragm regions are produced thereupon. Instead of using porous silicon, a plasma etching process may be performed from the backside of a semiconductor material substrate. In particular, high integration densities of diaphragm sensors may be achieved with both methods. A diaphragm sensor array is produced by one of the methods.

    Abstract: Efficient methods for lithographically fabricating spring structures onto a substrate containing contact pads or metal vias by forming both the spring metal and release material layers using a single mask. Specifically, a pad of release material is self-aligned to the spring metal finger using a photoresist mask or a plated metal pattern, or using lift-off processing techniques. A release mask is then used to release the spring metal finger while retaining a portion of the release material that secures the anchor portion of the spring metal finger to the substrate. When the release material is electrically conductive (e.g., titanium), this release material portion is positioned directly over the contact pad or metal via, and acts as a conduit to the spring metal finger in the completed spring structure. When the release material is non-conductive, a metal strap is formed to connect the spring metal finger to the contact pad or metal via, and also to further anchor the spring metal finger to the substrate.

    Abstract: A dissolved wafer micromachining process is modified by providing an etch control seal around the perimeter of a heavily doped micromechanical structure formed on a substrate. The micromechanical structure is fabricated on a wafer using conventional methods including the formation of a trench that surrounds and defines the shape of the micromechanical structure in the substrate. The etch control seal comprises a portion of the substrate in the form of a raised ring extending around the perimeter of the micromechanical structure and its defining trench. Selected raised areas of the heavily doped micromechanical structure and the top of the raised etch control seal are bonded to a second substrate. A selective etch is then used to dissolve the first substrate so that the heavily doped micromechanical structure remains attached to the second substrate only at the bonded areas. The etch control seal reduces exposure of the micromechanical structure and bonded areas to the etch by preventing the etch from contacting the heavily doped structure until the etch leaks through the dissolving floor of the trench. This occurs only during the final stages of the substrate dissolution step, thus minimizing exposure of the micromechanical structure and bonded areas to the damaging effects of the etch. Use of an etch control seal increases design flexibility and improves micromechanical device yield and quality in a dissolved wafer fabrication process.
