Abstract:
To provide a process for producing a wiring substrate with conduction failure in a hole formed in an electrical insulator layer suppressed even without conducting an etching treatment using metal sodium, and with unexpected deformation such as warpage suppressed even when the electrical insulator layer contains no woven fabric or non-woven fabric comprising reinforcing fibers. A process for producing a wiring substrate  1 , which comprises forming a hole  20  in a laminate comprising a first conductor layer  12 , an electrical insulator layer  10  which contains a specific fluororesin layer (A)  16  and a heat resistant resin layer (B)  18 , contains no reinforcing fiber to substrate, and has a dielectric constant of from 2.0 to 3.5 and a linear expansion coefficient of from 0 to 35 ppm/° C., and a second conductor layer  14 , applying, to an inner wall surface  20 a  of the hole  20 , either one or both of a treatment with a permanganic acid solution and a plasma treatment without conducting an etching treatment using metal sodium, and then forming a plating layer  22  on the inner wall surface  20 a  of the hole  20.

Claim (Index 2):
A process for producing a wiring substrate comprising an electrical insulator layer, a first conductor layer formed on a first surface of the electrical insulator layer and a second conductor layer formed on a second surface opposite from the first surface of the electrical insulator layer, and having a hole which opens at least from the first conductor layer through the second conductor layer and a plating layer formed on an inner wall surface of the hole; wherein\n the electrical insulator layer has a multi-layered structure containing at least one fluororesin layer (A) containing a melt-moldable fluororesin (a) having at least one type of functional groups selected from the group consisting of carbonyl group-containing groups, hydroxy groups, epoxy groups and isocyanate groups, and at least one heat resistant resin layer (B) containing a heat resistant resin (b) (excluding the fluororesin (a)), contains no reinforcing fiber substrate made of woven fabric or non-woven fabric, and has a dielectric constant of from 2.0 to 3.5 and a linear expansion coefficient of from 0 to 35 ppm/\u00b0 C.; the process comprising forming the hole in a laminate comprising the electrical insulator layer and the second conductor layer; applying, to the inner wall surface of the hole formed, either one or both of a treatment with a permanganic acid solution and a plasma treatment without conducting an etching treatment using metal sodium, then forming the plating layer on the inner wall surface of the hole, and forming the first conductor layer on the first surface of the to electrical insulator layer.
