Abstract: A coupling device with electro-magnetic compensation is provided. The coupling device includes a first substrate having a first signal line on a top surface of the first substrate and a second substrate having a second signal line on a top surface of the second substrate connected together with a bottom surface of the first substrate wherein the second signal line couples with the first signal line by a plurality of electrical-conductive through holes. One side of the first signal line lies a capacitor device parallel connected to a ground and the capacitor device plays the role of adjusting the amount of return loss, isolation capacity, and coupling effect so as to have transmitting speeds in first and second signal lines remain substantially the same and superior high frequency characteristics.

Abstract: A method of fabricating a thermal conductive plug of a ceramic substrate of a multi-chip package. A plurality of conductive openings and thermal conductive openings are formed on green tapes. A metal paste is filled into the conductive openings and the thermal conductive openings. The green tapes are stacked together so that the metal paste inside the conductive openings and the thermal conductive openings of every green tape is in contact respectively with its neighboring metal paste within the conductive openings and thermal conductive openings of the green tapes. Cofire those green tapes and the metal paste to form a pre-substrate. The pre-substrate comprises an insulating structure, a plurality of thermal conductive plugs and conductive plugs.

Abstract: A method for fabricating a multi-layer ceramic substrate is disclosed. The method compresses multi-layer green tapes by a mold apparatus having an upper mold and a lower mold. The method provides a carrying board and multi-layer green tapes over the lower mold. The method compresses the green tapes by the upper mold and the lower mold. The green tapes are parted from the upper mold. The carrying board is parted from the lower mold. The carrying board is parted from the green tapes.

Abstract: In a lamination process, a plurality of substrate layers are stacked on one another, a topmost substrate layer having an opening therein. A fill material is formed under liquid form in the opening, and is solidified. Thereafter, the substrate layers are heated and pressed between two pressing plates in a press-bonding process, the fill material receiving a pressure of the pressing plates. The pressing plates have planar pressing surfaces, which therefore prevents alteration of the cavity shape and size.
