Latest Patents

Arai's latest patents focus on advanced wiring substrates and semiconductor devices. One patent describes a wiring substrate designed with a wiring layer and an insulation layer that covers it, featuring an opening that partially exposes the wiring layer. This innovative design includes a seed layer that continuously covers the wall surface of the opening and the upper surface of the insulation layer. The construction is further enhanced by a metal layer, a metal post, and an outer coating plating layer, where the side portion is notably thinner than the upper portion.

Another patent introduces a wiring substrate with first wiring portions and an insulation layer covering them. In this design, openings extend through the insulation layer, partially exposing the upper surfaces of the first wiring portions. Differentiated by capacity, each of the second wiring portions contains via wiring and a connection terminal on the upper surface of the insulation layer. The via wiring incorporates an electrolytic plated layer along with an electroless plating structure, which increases in thickness relative to the capacity of the openings filled.
