Abstract: An ultrasonic back suction-integrated tooth cleaner includes a tooth cleaner host and a tooth cleaner handle. The tooth cleaner host includes a pipeline structure inside. Head ends of a water supply pipeline and a back suction pipeline both extend out of a housing of the tooth cleaner host and are connected to a tail end of the tooth cleaner handle. In the present invention, a back suction pipeline is added to an existing tooth cleaner host, so that the host is adapted to an integral tooth cleaner handle with a back suction function. A flow rate in the water supply pipeline is regulated by using an electromagnetic valve, so that a requirement for accurately controlling a water output volume is satisfied. The tooth cleaner handle is ingeniously designed with a back suction pipeline inside the existing ultrasonic handle, so that an aerosol is effectively controlled during ultrasonic tooth cleaning.

Abstract: A III-nitride-based semiconductor wafer is provided that includes a substrate with a central region and a peripheral edge region. One or more intermediate layers may be optionally provided selected from a buffer layer, a seed layer, or a transition layer. A peripheral edge feature is formed in or on a peripheral edge region of the substrate or the transition layer, with one or more peripheral edge passivation layers or peripheral edge surface texturing. The peripheral edge feature extends only around the peripheral edge and not in the central region. One or more III-nitride-based layers is positioned over the central region. In the central region, the III-nitride layer is an epitaxial layer while in the peripheral edge region, it is a polycrystalline layer. Stress due to lattice mismatches and differences in the coefficient of thermal expansion between the III-nitride layer and the substrate is relieved, minimizing defects.
