The present invention provides a nonwoven fabric material prepared from short fibers (1) including thermal-resistant synthetic fibers bound with an inorganic binder (2), a prepreg and a circuit board using the same. The circuit board has an excellent dimensional stability even at a high temperature, and the circuit board is prevented from warping or being damaged by moisture absorption or the like. The inorganic binder (2) is a residue formed from a low melting point glass solution or a water-dispersible colloidal solution including at least either fibers or particles of low melting point glass dispersed therein. When the binder is used, a chemical covalent bonding by a siloxane bonding is formed.
Abstract:
A method for fabricating a flexible interconnect film includes applying a resistor layer (16,18) over one or both surfaces of a dielectric film (10); applying a metallization layer (22) over the resistor layer with the resistor layer including a material facilitating adhesion of the dielectric film and the metallization layer; applying a capacitor dielectric layer (24a) over the metallization layer; and applying a capacitor electrode layer (26a) over the capacitor dielectric layer. The capacitor electrode layer is patterned to form a first capacitor electrode; the capacitor dielectric layer is patterned; the metallization layer is patterned to form a resistor (28); and the metallization layer and the resistor layer are patterned to form an inductor (33) and a second capacitor electrode. In one embodiment, the dielectric film includes a polyimide, the resistor layer includes tantalum nitride, and the capacitor dielectric layer includes amorphous hydrogenated carbon or tantalum oxide. If the resistor and metallization layers are applied over both surfaces of the dielectric film, passive components can be fabricated on both surfaces of the dielectric film. The dielectric film can have vias therein with the resistor and metallization layers extending through the vias. A circuit chip can be attached and coupled to the passive components by metallization patterned through vias in an additional dielectric layer.
