    摘要： This invention is to propose a technique of producing a printed wiring board having an excellent adhesion property between an electroless plated film and an electrolytic plated film constituting a conductor circuit through a semi-additive process without causing the peeling of a plating resist and is a printed wiring board comprising conductor circuits formed on a roughened surface of an insulating layer, in which the conductor circuit is constituted with an electroless plated film at the side of the insulating layer and an electrolytic plated film at the opposite side and the electroless plated film located at the side of the insulating layer is formed so as to follow to the roughened surface of the insulating layer. This printed wiring board is produced by a semi-additive method wherein the electroless plated film is formed on the roughened surface of the insulating layer so as to follow to the roughened surface of the insulating layer.

    摘要： A multilayer printed-circuit board is provided which is formed by stacking one on the other a plurality of circuit boards, each including a hard insulative substrate having a conductor circuit formed on one or either side thereof, and having formed therein via-holes formed through the hard insulative substrate to extend to the conductor circuit and each filled with a conductive substance, with an adhesive applied between the plurality of circuit boards, and heating and pressing the circuit boards together. One of the outermost ones of the stacked circuit boards has formed on the surface thereof conductive bumps each positioned right above the via-hole and electrically connected to the via-hole, and the other outermost one of the stacked circuit boards has formed on the surface thereof conductive pin or balls each positioned right above the via-hole and electrically connected to the via-hole. This multilayer printed-circuit board is used as a package circuit board and electronic components such as LSI chip are mounted on it to form a semiconductor device. The multilayer printed-circuit board is used as a core substrate, and a build-up wiring layer is formed on one or either side of the core multilayer circuit board. Solder bumps are formed on the surface of one outermost conductor circuit of the build-up wiring layer and conductive pins or balls are provided on the surface of the other outermost conductor circuit of the build-up wiring layer. Thus, a multilayer printed-circuit board is provided on which wiring can be made densely and also electronic components can be mounted with a high density.
