Latest Patents

One of Okabe's latest patents is focused on a semiconductor device and its manufacturing method. This invention addresses the issue of high connection resistance values between wiring layers caused by oxide films. By embedding a first metal layer in opening regions that connect the first and second wiring layers, and forming an opening in a spin-coated resin film, Okabe's design enhances connectivity. The structure allows for a coarse Cr layer on the first metal layer, which reduces the connection resistance value through the formation of an alloy layer with a second metal layer and a Cu plated layer.

Another significant patent involves a semiconductor device where multiple opening regions are created in an insulating film on a pad electrode. The metal layer on the pad electrode features concave portions that interact with a Cu plating layer. This innovative design reduces the resistance value on the pad electrode by utilizing the metal reaction area as a current path.
