Abstract: A device includes: a complementary transistor including: a first transistor having a first source/drain region and a second source/drain region; and a second transistor stacked on the first transistor, and having a third source/drain region and a fourth source/drain region, the third source/drain region overlapping the first source/drain region, the fourth source/drain region overlapping the second source/drain region. The device further includes: a first source/drain contact electrically coupled to the third source/drain region; a second source/drain contact electrically coupled to the second source/drain region; a gate isolation structure adjacent the first and second transistors; and an interconnect structure electrically coupled to the first source/drain contact and the second source/drain contact.

Abstract: A vacuum breaker includes a main body, a bushing mounted in the main body, a braking member mounted in the main body and located above the bushing, a water stop gasket mounted in the main body and located above the braking member, an elastic member mounted in the main body and biased between the bushing and the braking member, a water inlet disk mounted in the main body and located above the water stop gasket, and a washer mounted in the main body and located above the water inlet disk. The vacuum breaker further includes a connection structure mounted between an inner circumference of the main body and an outer circumference of the bushing. The bushing is combined integrally with the main body by the connection structure under an external force and will not be detached from the main body.

Abstract: A vacuum breaker includes a main body, a bushing, an elastic member, a braking member, a water stop gasket, a water inlet disk and a washer. The interior of the main body is provided with a positioning groove. The bushing is made of metallic material and has an exterior provided with a positioning protrusion secured in and combined integrally with the positioning groove of the main body. The bushing is extruded outward by an oil pressure to form the positioning protrusion. Thus, the bushing is combined with the main body integrally and will not be detached from the main body.

Abstract: A hydrant device includes a faucet body, a rotation shaft, an upper rotation cap, a check valve, a switch valve, a lower fixed cap, and a water intake seat. The faucet body is provided with a rotary knob connected with the rotation shaft which is connected with the upper rotation cap. A first elastic member is biased between the rotation shaft and the upper rotation cap. A second elastic member is biased between the upper rotation cap and the check valve. The check valve is provided with a stop face. The switch valve is combined with the upper rotation cap. The water intake seat is mounted on the faucet body. Thus, the stop face forms an anti-reverse state to seal the switch valve, thereby preventing water from being gathered in the switch valve.

Abstract: A vacuum breaker includes a safe valve body and an elastic gasket. The safe valve body has a receiving space which has a periphery provided with connecting holes. The elastic gasket has a size smaller than that of the receiving space, with clearances being defined between the elastic gasket and the receiving space. The elastic gasket has a center provided with a through hole and has an outer periphery provided with a sealing portion. Thus, the sealing portion contracts inward when water stops passing the safe valve body, so that ambient air flows into the receiving space to break a vacuum state in the safe valve body, such that a fluid contained in the safe valve body flows through the clearances between the elastic gasket and the safe valve body, and is drained outward from the connecting holes.
