Latest Patents

Shioi’s recent patent work addresses both the materials used in acoustic wave devices and the design of resonators.

“Acoustic Wave Device and Method for Producing Same” describes a manufacturing process that uses heat treatment to form a polycrystalline spinel layer on a sapphire substrate. The process includes polishing the sapphire, applying magnesium oxide or magnesium oxide powder, heat-treating the materials at 1300°C to 1600°C, removing the magnesium oxide, and polishing the spinel layer before forming a piezoelectric substrate on it.

“Acoustic Wave Device and Module Including the Same” describes an acoustic wave device with series and parallel resonators formed on a piezoelectric layer. Its design assigns different anti-resonance frequencies to series-divided resonators in two series-resonator groups, with the frequency assignments varying according to each resonator’s position.
