A method of making a circuitized substrate which includes at least one and possibly several capacitors as part thereof. In one embodiment, the substrate is produced by forming a layer of capacitive dielectric material on a dielectric layer and thereafter forming channels with the capacitive material, e.g., using a laser. The channels are then filled with conductive material, e.g., copper, using selected deposition techniques, e.g., sputtering, electro-less plating and electroplating. A second dielectric layer is then formed atop the capacitor and a capacitor 'core' results. This 'core' may then be combined with other dielectric and conductive layers to form a larger, multilayered PCB or chip carrier. In an alternative approach, the capacitive dielectric material may be photo-imageable, with the channels being formed using conventional exposure and development processing known in the art.

Substrate having internal capacitor and method of making same

Methods of forming embedded, multilayer capacitors in printed circuit boards wherein copper or other electrically conductive channels are formed on a dielectric substrate. The channels may be preformed using etching or deposition techniques. A photoimageable dielectric is an upper surface of the laminate. Exposing and etching the photoimageable dielectric exposes the space between the copper traces. These spaces are then filled with a capacitor material. Finally, copper is either laminated or deposited atop the structure. This upper copper layer is then etched to provide electrical interconnections to the capacitor elements. Traces may be formed to a height to meet a plane defining the upper surface of the dielectric substrate or thin traces may be formed on the remaining dielectric surface and a secondary copper plating process is utilized to raise the height of the traces.

Circuitized substrate with internal cooling structure and electrical assembly utilizing same

A method of making a circuitized substrate (e.g., PCB) including at least one and possibly several internal optical pathways as part thereof such that the resulting substrate will be capable of transmitting and/or receiving both electrical and optical signals. The method involves forming at least one opening between a side of the optical core and an adjacent upstanding member such that the opening is defined by at least one angular sidewall. Light passing through the optical core material (or into the core from above) is reflected off this angular sidewall. The medium (e.g., air) within the opening thus also serves as a reflecting medium due to its own reflective index in comparison to that of the adjacent optical core material. The method utilizes many processes used in conventional PCB manufacturing, thereby keeping costs to a minimum. The formed substrate is capable of being both optically and electrically coupled to one or more other substrates possessing similar capabilities, thereby forming an electro-optical assembly of such substrates.
