    摘要: A printed circuit polymer thick film (PTF) resistor includes tolerance control material that substantially surrounds the resistor body and significantly improves the linearity of resistance vs. resistor length, and significantly reduces resistor-to-resistor and board-to-board fabrication variances. In one embodiment, the tolerance control material is the same metallic material as the printed circuit conductors, and is formed in two finger patterns on each side of the resistor body, each finger pattern connected to one terminal pad of the resistor. A layout cell is used for fabricating the PTF resistor. A method is used for fabricating the PTF resistor.

    摘要: A method for manufacturing a microelectronic assembly to have a resistor, and particularly a metal resistive film, with desirable processing and dimensional characteristics. The method generally entails applying a photosensitive dielectric to a substrate to form a dielectric layer. The dielectric layer is photoimaged to polymerize a first portion of the dielectric layer on a first region of the substrate, leaving the remainder of the dielectric layer unpolymerized. An electrically resistive film is then applied to the dielectric layer, and the dielectric layer is developed to remove concurrently the unpolymerized portion thereof and the portion of the resistive film overlying the unpolymerized portion, so that a portion of the resistive film remains over the second portion to form the resistor. An alternative process order is to apply the resistive film prior to exposing the dielectric layer to radiation, and then exposing the dielectric layer through the resistive film. The resistive film is preferably a multilayer film that includes an electrically resistive layer, such as NiP, NiCr or another nickel-containing alloy, and a sacrificial backing such as a layer of copper.

    摘要: A method is for fabricating an embedded capacitance printed circuit board assembly (400, 1100). The embedded capacitance printed circuit board assembly includes two embedded capacitance structures (110). Each capacitance structure (110) includes a crystallized dielectric oxide layer (115) sandwiched between an outer electrode layer (120) and an inner electrode layer (125) in which the two inner electrode layers are electrically connected together. A rivet via (1315) and a stacked via (1110) formed from a button via (910) and a stacked blind via (1111) may be used to electrically connect the two inner electrode layers together. A spindle via (525) may be formed through the inner and outer layers. The multi-layer printed circuit board may be formed from a capacitive laminate (100) that includes two capacitance structures.

    摘要: A technique for fabricating a patterned resistor on a substrate produces a patterned resistor (101, 801, 1001, 1324, 1374) including two conductive end terminations (110, 810, 1010) on the substrate, a pattern of first resistive material (120, 815, 1015) having a first width (125) and a first sheet resistance, and a pattern of second resistive material (205, 820, 1020) having a second width (210) and a second sheet resistance that at least partially overlies the pattern of first resistive material. One of the first and second sheet resistances is a low sheet resistance and the other of the first and second resistances is a high sheet resistance. A ratio of the high sheet resistance to the low sheet resistance is at least ten to one. The pattern having the higher sheet resistance is substantially wider than the pattern having the low sheet resistance. The patterned resistor can be precision trimmed 1225.
