RF and microwave radiation directing or controlling components are provided that may be monolithic, that may be formed from a plurality of electrodeposition operations and/or from a plurality of deposited layers of material, that may include switches, inductors, antennae, transmission lines, filters, hybrid couplers, antenna arrays and/or other active or passive components. Components may include non-radiation-entry and non-radiation-exit channels that are useful in separating sacrificial materials from structural materials. Preferred formation processes use electrochemical fabrication techniques (e.g. including selective depositions, bulk depositions, etching operations and planarization operations) and post-deposition processes (e.g. selective etching operations and/or back filling operations).
Abstract:
Electrochemical fabrication processes and apparatus for producing multi-layer structures where each layer includes the deposition of at least two materials and wherein the formation of at least some layers including operations for providing coatings of dielectric material that isolate at least portions of a first conductive material from (1) other portions of the first conductive material, (2) a second conductive material, or (3) another dielectric material, and wherein the thickness of the dielectric coatings are thin compared to the thicknesses of the layers used in forming the structures. In some preferred embodiments, portions of each individual layer are encapsulated by dielectric material while in other embodiments only boundaries between distinct regions of materials are isolated from one another by dielectric barriers.

Abstract:
Numerous electrochemical fabrication methods and apparatus are provided for producing multi-layer structures (e.g. having meso-scale or micro-scale features) from a plurality of layers of deposited materials using adhered masks (e.g. formed from liquid photoresist or dry film), where two or more materials may be provided per layer where at least one of the materials is a structural material and one or more of any other materials may be a sacrificial material which will be removed after formation of the structure. Materials may comprise conductive materials that are electrodeposited or deposited in an electroless manner. In some embodiments special care is undertaken to ensure alignment between patterns formed on successive layers.
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 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 the tip material around carefully sized and placed etching shields, via hot pressing, and the like.
Abstract:
Electrochemical fabrication processes and apparatus for producing single layer or multi-layer structures where each layer includes the deposition of at least two materials and wherein the formation of at least some layers includes operations for reducing stress and/or curvature distortion when the structure is released from a sacrificial material which surrounded it during formation and possibly when released from a substrate on which it was formed. Six primary groups of embodiments are presented which are divide into eleven primary embodiments. Some embodiments attempt to remove stress to minimize distortion while others attempt to balance stress to minimize distortion.
Abstract:
Multi-layer, multi-material fabrication methods include depositing at least one structural material and at least one sacrificial material during the formation of each of a plurality of layers wherein deposited materials for each layer are planarized to set a boundary level for the respective layer and wherein during formation of at least one layer at least three materials are deposited with a planarization operation occurring before deposition of the last material to set a planarization level above the layer boundary level and wherein a planarization occurs after deposition of the last material level above the layer boundary level and wherein a planarization occurs after deposition of the last material whereby the boundary level for the layer is set. Some formation processes use electrochemical fabrication techniques (e.g. including selective depositions, bulk depositions, etching operations and planarization operations) and post-deposition processes (e.g. selective etching operations and/or back filling operations).
Abstract:
Embodiments are directed to forming reentrant multi-layer micro-scale or millimeter scale three dimensional structures, parts, components, or devices where each layer is formed from a plurality of deposited materials and more specifically where each layer is formed from at least one metal structural material and at least one organic sacrificial material (e.g. polymer) that are co-planarized and a portion of the sacrificial material located on a plurality of layers is removed after formation of the plurality of layers via one or more plasma etching operations or one or more neutral radical etching operations.

Abstract:
Some embodiments are directed to techniques for building single layer or multi-layer structures on dielectric or partially dielectric substrates. Certain embodiments deposit seed layer material directly onto substrate materials while others use an intervening adhesion layer material. Some embodiments use different seed layer and/or adhesion layer materials for sacrificial and structural conductive building materials. Some embodiments apply seed layer and/or adhesion layer materials in what are effectively selective manners while others apply the materials in blanket fashion. Some embodiments remove extraneous material via planarization operations while other embodiments remove the extraneous material via etching operations. Other embodiments are directed to the electrochemical fabrication of multilayer mesoscale or microscale structures which are formed using at least one conductive structural material, at least one conductive sacrificial material, and at least one dielectric material. In some embodiments the dielectric material is a UV-curable photopolymer.
