Latest Patents

One of his latest patents is a semiconductor device that features an active element connected to an electrode metal pad via a barrier metal layer and interlayer insulating film. This invention includes an active element on a semiconductor substrate, an interlayer insulating film covering the active element, and a pad metal for an electrode pad situated on the interlayer insulating film. The design incorporates a barrier metal layer positioned between the active element and the interlayer insulating film, ensuring that the pad metal is formed on the barrier metal layer. Additionally, an insulating layer with high adherence to the barrier metal layer is placed between the interlayer insulating film and the barrier metal layer. This arrangement significantly enhances the adherence between the barrier metal layer, the insulating film, and the interlayer insulating film. As a result, even when external forces are applied to the electrode pad during bonding or afterward, the barrier metal layer remains securely attached. This innovation prevents breakdowns and exfoliation, allowing for the mass production of semiconductor devices that are cost-effective, high-quality, and reliable. Furthermore, the yield of these semiconductor devices is notably improved.
