Abstract: A semiconductor device and method of manufacturing the same are provided. The semiconductor device includes a first active region extending along a first direction. The semiconductor device also includes a second active region extending along the first direction. The semiconductor device further includes a first gate extending along a second direction perpendicular to the first direction. The first gate has a first segment disposed between the first active region and the second active region. In addition, the semiconductor device includes a first electrical conductor extending along the second direction and across the first active region and the second active region, wherein the first segment of the first gate and the first electrical conductor are partially overlapped to form a first capacitor.

Abstract: A self-priming centrifugal pump has a recirculation tube connected between a hollow cylinder having a first set of impellers received therein and a first tube having liquid received therein and having a second set of impellers received in one end thereof, so that the suction lift of liquid is enhanced and the liquid flow subjected only to the gravity will also be expedited by the extra centrifugal effect created by the second impeller. Furthermore, there are provided with a plurality of through holes communicating with the first tube. Therefore, the amount of liquid flow back to the first tube is increased.
