Abstract: A semiconductor structure includes a first semiconductor structure and a second semiconductor structure. The method of bonding a semiconductor structure includes performing a surface treatment on a first surface of the first semiconductor structure and a second surface of the second semiconductor structure based on a first gas and a second gas. The first gas excites at least one of the first surface or the second surface to generate a free radical. The second gas is excited to generate a plasma gas. A free negative ion in the plasma gas is combined with the free radical. The method also includes performing a face-to-face bonding on the first surface and the second surface.

Abstract: A trench field-effect transistor (FET) device includes a plurality of active trenches extending along a first axis and distributed along a second axis perpendicular to the first axis. Each active trench includes a gate electrode and a shield electrode. The trench FET device further includes a plurality of termination trenches fully filled with a dielectric material, extending along the second axis, and arranged adjacent to the active trenches. In addition, the shield electrode of each of the active trenches abuts a respective one of the plurality of termination trenches at each end.

Abstract: An optical coherence tomography device includes a base with a detection end and a mounting end, a movable base and a second drive mechanism. An optical imaging catheter is pivotally connected to the detection end. The optical imaging catheter is provided with an imaging end and a connecting end. The connecting end is detachably connected to the detection end, and the connecting end is provided with a first connecting part. The movable base is provided with a fiber optic rotary joint, a hollow shaft and a first drive mechanism. The end of the hollow shaft is provided with a second connecting part. When the movable base moves toward the detection end, the second connecting part is configured to be connected to the first connecting part so that the optical imaging catheter is coupled with the hollow shaft. The device is capable of manually or automatically connecting the optical imaging catheter.
