Abstract:
A wiring board structure comprising:a board made of a material etched by a given solution;an inner conductive device disposed within said board and having a first portion extending parallel to a surface of said board and a second portion connected to said first portion, said second portion extending perpendicular to and past said surface of said board;an insulating layer having a portion which is in contact with said surface of said board and in contact with only a side surface of said second portion of said inner conductive device extending past said surface of said board;an electrically conductive layer disposed on top of said insulating layer and connected to an exposed surface of said second portion of said inner conductive device;a second insulating layer disposed over said electrically conductive layer and having a window via hole located over said second portion of said inner conductive device; anda surface conductive layer disposed over said second insulating layer, extending into said window via hole in said second insulating layer, and contacting said electrically conductive layer,wherein said insulating layer prevents a gap etched between said electrically conductive layer and said board.
