Hiroaki Sano's latest patents include advanced wiring board designs. One of his patents describes a wiring board that features an insulation layer made of ceramic, with an electrical conductor layer extending in a planar direction inside the insulation layer. This electrical conductor layer is constituted by a sintered body of multiple crystallites containing a metal as a main component. The patent specifies that when a specific range of the electrical conductor layer is examined in a cross-sectional view, a linear length in the planar direction is defined as L0, while the length of the contour of the electrical conductor layer is defined as L1. The ratio L1/L0 is maintained within a range from 1.04 to 1.40. Another patent outlines a wiring board that includes an insulation layer and an electrical conductor layer that are layered. In this design, the insulation layer is made of glass ceramic, and the electrical conductor layer is a sintered body of crystallites primarily composed of copper. The crystallites are polygonal with linear sides and are in contact with each other at their grain boundaries.
