Abstract

1379558 Printed circuits INTERNATIONAL COMPUTERS Ltd 12 May 1972 [15 May 1971] 15155/71 Heading H1R A multilayer circuit is built up in stages. A laser beam (Fig. 3, not shown) makes 130 Ám diameter holes 13 in a 200 Ám thick epoxy fibreglass substrate 11 carrying a layer 10 of conductors. The holes are cleaned and then filled electrolytically with copper 14. A 500 nm conductive layer 15 is formed. A photoresist mask 16 is applied. Areas 17 are then plated up to 25 Ám thickness. The mask 16 is removed by a solvent. The layer 15 is removed, by rinsing in a weak etchant, except where it forms parts of the desired conductive areas 17. Another insulating layer 21 is stuck on, and the above steps are repeated, as often as required. In an alternative process the layer 15 is plated up to 25 Ám thickness, a different mask 16 is applied, and the unwanted parts of the layer 15 are etched away. If desired a hole can be formed and an interconnection made through more than one insulating layer.
