  • Patent number: 9935353
    Abstract: A conductor in a laminar structure, such as a printed circuit board or thin-film stack, is closely flanked by at least one open trench filled with an ambient medium (e.g., air, another gas, vacuum) of a lower dielectric loss than the conductor's surrounding dielectric. The trench may be made by any suitably precise method such as laser scribing, chemical etching or mechanical displacement. A thin layer of dielectric may be left on the sides of the conductor to prevent oxidation or other reactions that may reduce conductivity. When the conductor carries a signal, part of an electric and/or magnetic field that would ordinarily travel through the surrounding dielectric encounters the low-loss ambient medium (e.g. air) in the trench. The effective dielectric loss surrounding the conductor is lowered, reducing signal attenuation and crosstalk, particularly at high frequencies.

    Abstract: A method of packaging a semiconductor die includes the steps of mounting the semiconductor die on a carrier, electrically connecting electrical contact pads of the semiconductor die to external electrical contacts, and encapsulating the die with a mold compound to form a packaged die. The packaged die is then thinned by using a dicing saw blade to trim the mold compound off of the top, non-active side of the package using a series of vertical cuts. This thinning step can be performed at the same time as a normal dicing step so no additional equipment or process steps are needed. Further, packages of varying thicknesses can be assembled simultaneously.

    Abstract: There is provided a semiconductor device that suppresses the occurrence of resin burrs and has favorable electrical connectivity and bond strength, and a manufacturing method for such semiconductor device. A resin-coated metal part is manufactured by forming an organic coating by depositing a material including functional organic molecules on a wiring lead composed of a metallic material. Each of the functional organic molecules includes a main chain, a first functional group having a metal bonding property, and a second functional group. The first functional group and the second functional group are provided at different ends of the main chain. Thereafter the functional organic molecules self-assemble by bonding of the first functional groups to metal atoms of the wiring lead. After performing the organic coating formation step, resin is adhered to a predetermined surface area of the wiring lead having the organic coating formed thereon.

  • Patent number: 8987921
    Abstract: A method for producing a component with at least one micro-structured or nano-structured element includes applying at least one micro-structured or nano-structured element to a carrier. The element has at least one area configure to make contact and the element is applied to the carrier such that the at least one area adjoins the carrier. The element is enveloped in an enveloping compound and the element-enveloping compound composite is detached from the carrier. A first layer comprising electrically conductive areas is applied to the side of the element-enveloping compound composite that previously adjoined the carrier. At least one passage is introduced into the enveloping compound. A conductor layer is applied to the surface of the passage and at least to a section of the layer comprising the first electrically conductive areas to generate a through contact, which enables space-saving contacting. A component is formed from the method.
