Abstract:
In an aspect, the present invention provides stretchable, and optionally printable, components such as semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed, and related methods of making or tuning such stretchable components. Stretchable semiconductors and electronic circuits preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention are adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.
Abstract:
Disclosed is an apparatus and method for a magnetic component. The magnetic component includes a substrate having a feature and a first conductive pattern disposed on the feature. The magnetic component also includes a permeability material disposed within the feature. A substrate material is disposed on the substrate to facilitate substantial enclosure of the permeability material between the substrate and the substrate material, where the substrate material has a second conductive pattern. The first conductive pattern and the second conductive pattern cooperate to be capable of facilitating magnetic properties of the permeability material.
Abstract:
According to a method for producing connection substrates for semiconductor chips, preferably PSGA (polymer stud grid array) substrates, a blank body (1), preferably a film, is heated and humps (3) and/or recesses are produced on at least one of its surfaces using an embossing roller. High temperature resistant thermoplastics, preferably LCPs (liquid crystal polymers), are used as the material for the substrate body. Their surface can preferably be provided with a metallic layer which is in turn provided with openings as an embossing aid.
Abstract:
According to the invention, an electrically insulating substrate (S1) is provided with a plurality of longitudinally extended, elevated waves (W1) on the underside thereof. The conductor pattern is applied on the underside of the substrate by means of laser structuring such that the terminal pads (P1) are arranged in a flat manner in the grid array, and each is situated in the crest area of a wave. The inventive pad grid array can be produced with a fine grid of, for example, 250 mu m.
Abstract:
An insulating disk (2) is disclosed made of electrically insulating and thermally conductive material. One side (8) of this insulating disk (2) is provided with a recess with the same cross-section as a component (4, 6). Thanks to the surface design of this insulating disk (2), the value of the extinction voltage of the partial discharge is thus considerably increased, as well as sliding discharge and flashover resistance.
Abstract:
A non-hermetic, three-dimensional, microwave semiconductor device carrier with integral waveguide couplers is disclosed. A molded plastic substrate (400) having a suitable dielectric constant and varying thickness comprises plated conductors (425) and locations (430) for receiving GaAs MMIC's (420). MMIC's are mounted to a metal backplate (405) and wire bonded to the plated conductors. The waveguide couplers (435) are integrally molded as part of the carrier substrate, and comprise plated through cylindrical members. Signals from a waveguide cavity (515) are coupled to the MMIC's by inserting the waveguide couplers into a waveguide port. The carrier and integral waveguide coupler together with a plated molded cover (410) forms a non-hermetic package providing pseudo-shielding cavities about the resident multiple semiconductor GaAs die. Transmission line impedance control is enhanced by varying the substrate thickness on a per conductor basis. Frequency of operation exceeds 12 gigahertz.
