Abstract: A method for forming a semiconductor structure is provided. The method for forming the semiconductor structure includes forming a fin structure over a substrate in a first direction, forming a first gate stack, a second gate stack and a third gate stack across the fin structure, removing the first gate stack to form a trench, depositing a cutting structure in the trench, and forming a first contact plug between the cutting structure and the second gate stack and a second contact plug between the second gate stack and the third gate stack. The fin structure is cut into two segments by the trench. A first dimension of the first contact plug in the first direction is greater than a second dimension of the second contact plug in the first direction.

Abstract: A levering device includes a coupling block, a gripper, an operating rod, and a constraint sleeve. The coupling block includes a coupling chamber, two guide slots in communication with the coupling chamber, an extension rod, and an axial hole axially cut through the extension rod in communication with the coupling chamber. The operating rod being axially movably inserted through the axial hole into a bearing chamber of a housing of a motor-driven water lifting device to stop against respective one end of a wheel axle of the motor-driven water lifting device. The gripper is attachable to the two guide slots of the coupling block and includes two gripper blocks and two claw bars respectively connected to the gripper blocks. The constraint sleeve is sleeved onto the coupling block to stop the two claw bars in the respective the guide slots.

Abstract: A switching regulator having a low start-up voltage includes a power stage and a switch control circuit. The switch control circuit includes a power control switch. The power control switch is formed by a low threshold voltage transistor having a first conductivity type in a semiconductor substrate. The low threshold voltage transistor having the first conductivity type includes a first lightly doped region having a second conductivity type which forms a channel region of the low threshold voltage transistor having the first conductivity type. The semiconductor substrate includes a second lightly doped region having the second conductivity type which is formed by a same manufacturing process as the first lightly doped region having the second conductivity type. The second lightly doped region having the second conductivity type forms adrift region of a high-voltage transistor having the second conductivity type in the semiconductor substrate.
