Latest Patents

One of Alireza Tajic's latest patents involves the development of top electrodes and dielectric spacer layers for bulk acoustic wave resonators. This patent discloses top electrodes on piezoelectric layers that feature a border (BO) region with a dual-step arrangement. The inner and outer steps are designed with increasing heights toward the peripheral edges of the top electrode. Additionally, dielectric spacer layers may be positioned between the outer steps and the piezoelectric layer. The patent also describes passivation layers that extend over the top electrode, either reaching the peripheral edges of the piezoelectric layer or inset from them. Furthermore, piezoelectric layers can be arranged with reduced thickness portions in areas that are not covered by top electrodes. The BAW resonators developed through this innovation are characterized by high quality factors and the suppression of spurious modes, while also providing weakened BO modes that are shifted farther away from the passbands of the resonators.
