    摘要: A conducting paste and method of forming the paste for device level interconnection. The conducting paste contains metal loading in the range 80-95% that is useful for making five micron device level interconnects. The conducting paste is made by mixing two different conducting pastes, each paste maintaining its micro level individual rich region in the mixed paste even after final curing. One paste contains at least one low melting point alloy and the other paste contains noble metal fillers such as gold or silver flakes. In general, average flake size below five micron is suitable for five micron interconnects. However, 1 micron or smaller silver flakes and an LMP mixture is preferred for five micron interconnects. The amount of LMP based paste in the final mixture is preferably 20-50% by weight. The nano micro paste embodiment shows good electrical yield (81%) and low contact resistance.

    摘要: A method of forming a circuitized substrate for use in electronic packages. A substrate layer is provided that has a copper pad on a surface. A conductive seed layer and a photoresist layer are placed on the surface. The photoresist is developed and conductive material is placed within the developed features and a second conductive material placed on the first conductive material. The photoresist and conductive seed layer are removed to leave a micro-pillar array. The joining and lamination of two circuitized substrate layers utilizes the micro-pillar array for the electrical connection of the circuitized substrate layers.

    摘要: 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.
