Abstract:
Various embodiments of the invention provide techniques for forming structures (e. g. HARMS-type structures) via an electrochemical extrusion process. Preferred embodiments perform the extrusion processes via depositions through anodeless conformable contact masks that are initially pressed against substrates that are then progressively pulled away or separated as the depositions thicken. A pattern of deposition may vary over the course of deposition by including more complex relative motion between the mask and the substrate elements. Such complex motion may include rotational components or translational motions having components that are not parallel to an axis of separation. More complex structures may be formed by combining the electrochemical extrusion process with the selective deposition, blanket deposition, planarization, etching, and multi-layer operations of a multi-layer electrochemical fabrication process.
Method For Extending Diamond Tool Life In Diamond Machining Of Materials That Chemically React With Diamond
The present invention provides a method for extending diamond tool life in diamond machining of materials that chemically react with the diamond tool in which the surface electric potential of the workpiece is adjusted or tuned to be adequate to inhibit the chemical reaction between the diamond tool and the workpiece during the diamond machining operation. As the chemical reaction is inhibited, the chemical wear rate of the diamond tool is reduced and diamond tool life is extended. The surface electric potential of the workpiece can be adjusted by electrically charging the workpiece. In one embodiment, conduction charging is used to adjust the surface electric potential of the workpiece to inhibit the chemical reaction between the diamond tool and the workpiece. In another embodiment, induction charging is used to adjust the surface electric potential of the workpiece to inhibit the chemical reaction between the diamond tool and the workpiece.

Abstract:
Multilayer structures are electrochemically fabricated via depositions of one or more materials in a plurality of overlaying and adhered layers. Selectivity of deposition is obtained via a multi-cell controllable mask. Alternatively, net selective deposition is obtained via a blanket deposition and a selective removal of material via a multi-cell mask. Individual cells of the mask may contain electrodes comprising depositable material or electrodes capable of receiving etched material from a substrate. Alternatively, individual cells may include passages that allow or inhibit ion flow between a substrate and an external electrode and that include electrodes or other control elements that can be used to selectively allow or inhibit ion flow and thus inhibit significant deposition or etching. Single cell masks having a cell size that is smaller or equal to the desired deposition resolution may also be used to form structures.

Abstract:
Embodiments of the present invention are directed to the formation of microprobe tips elements having a variety of configurations. In some embodiments tips are formed from the same building material as the probes themselves, while in other embodiments the tips may be formed from a different material and/or may include a coating material. In some embodiments, the tips are formed before the main portions of the probes and the tips are formed in proximity to or in contact with a temporary substrate. Probe tip patterning may occur in a variety of different ways, including, for example, via molding in patterned holes that have been isotropically or anisotropically etched silicon, via molding in voids formed in over exposed photoresist, via molding in voids in a sacrificial material that have formed as a result of the sacrificial material mushrooming over carefully sized and located regions of dielectric material, via isotropic etching of a the tip material around carefully sized placed etching shields, via hot pressing, and the like.
