摘要:
A circuitized substrate with a conductive layer which assures enhanced adhesion of the layer to selected dielectric layers used to form the circuitized substrate. The conductive layer includes at least one surface with the appropriate roughness to enable such adhesion and also good signal passage if the layer is used as a signal layer.
摘要:
A method of treating a conductive layer to assure enhanced adhesion of the layer to selected dielectric layers used to form a circuitized substrate. The conductive layer includes at least one surface with the appropriate roughness to enable such adhesion and also good signal passage if the layer is used as a signal layer. The method is extendible to the formation of such substrates, including to the formation of multilayered substrates having many conductive and dielectric layers. Such substrates may include one or more electrical components (e.g., semiconductor chips) mounted thereon and may also be mounted themselves onto other substrates.
摘要:
A method of making a circuitized substrate which includes a high temperature dielectric material in combination with a low temperature conductive paste, the paste including an organic binder component and at least one metallic component. The flakes of the metallic component are sintered to form a conductive path through the dielectric when the dielectric is used as a layer in the substrate.

摘要:
A method of making a multilayered circuitized substrate assembly which includes bonding at least two circuitized substrates each including at least one layer of high temperature dielectric material, one of these layers in turn including at least one thru-hole therein having therein a quantity of a a low temperature conductive paste, the paste including an organic binder component and at least one metallic component. The flakes of the metallic component are sintered during the bonding to form a conductive path through the dielectric of one of the substrates.

摘要:
A method for improving the adhesion between polyimide layers and the structure formed by the method. A silicon oxide-containing layer is formed on the surface of a polyimide layer and a second layer of polyimide is formed on the silicon oxide-containing layer.
摘要:
An electrically conductive adhesive (ECA) with low and stable contact resistance includes at least one melt-processable reactive resin, at least one reactive diluent, at least one rheological additive, copper particles, at least one curing agent and at least one organic acid catalyst. The ECA is useful for filling vias, and bonding together components of electronic circuit structures.
