Abstract:
Embodiments that allow multi-chip interconnect using organic bridges are described. In some embodiments an organic package substrate has an embedded organic bridge. The organic bridge can have interconnect structures that allow attachment of die to be interconnected by the organic bridge. In some embodiments, the organic bridge comprises a metal routing layer, a metal pad layer and interleaved organic polymer dielectric layers but without a substrate layer. Embodiments having only a few layers may be embedded into the top layer or top few layers of the organic package substrate. Methods of manufacture are also described.
Abstract:
The invention relates to a layer system comprising a contact element (5) and a substrate (1). A multilayer system (14) that is disposed on the substrate (1) has at least one top layer (3; 4) and a bottom layer (2; 3) as well as a contact element (5) which penetrates the at least one top layer (3; 4) and contacts the bottom layer (2; 3). The invention further relates to a method for producing a contact element (5) of a multilayer system (14).
Abstract:
Via holes are formed in a continuous inline shadow mask production system by depositing a first conductor layer and subsequently depositing a first insulator layer over a portion of the first conductor layer. The first insulator layer is deposited in a manner to define at least one notch along its edge. The second insulator layer is then deposited on another portion of the first conductor layer in a manner whereupon the second insulator layer slightly overlaps each notch of the first insulator layer, thereby forming the one or more via holes. A conductive filler can optionally be deposited in each via hole. Lastly, a second conductive layer can be deposited over the first insulator layer, the second insulator layer and, if provided, the conductive filler.
Abstract:
Method for manufacturing a parylene-based electrode array that includes an underlying parylene layer, one or more patterned electrode layers comprising a conductive material such as a metal, and one or more overlying parylene layers. The overlying parylene is etched away or otherwise processed to expose the electrodes where stimulation or recording is to occur. All other conductive material in the device is occluded from the environment by the two layers of parylene surrounding it.
Abstract:
A method of manufacturing a patterned electric circuit. The method comprises the steps of providing a cold gas-dynamic spraying (CGDS) device, providing a substrate, and depositing a pattern of electrically conductive material with the CGDS device on the substrate by relative movement between the CGDS device to the substrate.
Abstract:
A low-EMI circuit which realizes a high mounting density by converting the potential fluctuation of a power supply layer with respect to a ground layer which occurs on switching an IC device etc., into Joule's heat in the substrate without using any parts as a countermeasure against the EMI. Its structure, a circuit board using it, and a method of manufacturing the circuit board are also disclosed. Parallel plate lines in which the Q-value of the stray capacitance between solid layers viewed from the power supply layer and ground layer is equivalently reduced and which are matchedly terminated by forming a structure in which a resistor (resistor layer) and another ground layer are provided in addition to the power supply layer and the ground layer on a multilayered circuit board. A closed shield structure is also disclosed. This invention can remarkably suppress unwanted radiation by absorbing the potential fluctuation (resonance) which occurs in a power supply loop by equivalently reducing the Q-value of the stray capacitance, absorbing the standing wave by the parallel plate lines matchedly terminated and, closing and shielding the parallel plate lines.
Abstract:
Thermal post vias are formed within a formed multilayer, high density interconnect including a base and plural layers of metal conductors (68, 72, 76) separated by dielectric material (70) by the steps of: removing in a single step dielectric material at predetermined sites of the thermal post vias to define substantially cylindrical post holes, and forming the thermal post vias by emplacing conductor material, such as metal, into the post holes so that the material fully occupies and fills up the holes.
Abstract:
A method of making a multilayer thin film structure on the surface of a dielectric substrate which includes the steps of: a) forming a multilayer thin film structure including the steps of: applying a first layer of dielectric polymeric material on the surface of a dielectric substrate, applying a second layer of dielectric polymeric material over the first layer of polymeric material wherein the second polymeric material is photosensitive, imagewise exposing and developing the second polymeric material to form a feature therein, the second layer feature in communication with at least one feature formed in the first polymeric material; and b) filling the features in the entire multilayer structure simultaneously with conductive material. Preferably, the first layer feature is a via and the second layer feature is a capture pad or wiring channel. Also disclosed is a multilayer thin film structure made by this method.
Abstract:
The present disclosure provides a method to provide a conductive bus bar on a patterned transparent conductor, such as ITO traces used for touch screen manufacturing. The method can be a cheaper and a more convenient technique to pattern a conductive metal or metal alloy, such as copper, silver, or a copper/silver/titanium alloy, on ITO electrodes in a roll-to-roll process.
