Abstract: The present disclosure relates to a CMOS image sensor having a multiple deep trench isolation (MDTI) structure, and an associated method of formation. In some embodiments, the image sensor comprises a boundary deep trench isolation (BDTI) structure disposed at boundary regions of a pixel region surrounding a photodiode. The BDTI structure has a ring shape from a top view and two columns surrounding the photodiode with the first depth from a cross-sectional view. A multiple deep trench isolation (MDTI) structure is disposed at inner regions of the pixel region overlying the photodiode, the MDTI structure extending from the back-side of the substrate to a second depth within the substrate smaller than the first depth. The MDTI structure has three columns with the second depth between the two columns of the BDTI structure from the cross-sectional view. The MDTI structure is a continuous integral unit having a ring shape.

Abstract: In some embodiments, the present disclosure relates to a device having a semiconductor substrate including a frontside and a backside. On the frontside of the semiconductor substrate are a first source/drain region and a second source/drain region. A gate electrode is arranged on the frontside of the semiconductor substrate and includes a horizontal portion, a first vertical portion, and a second vertical portion. The horizontal portion is arranged over the frontside of the semiconductor substrate and between the first and second source/drain regions. The first vertical portion extends from the frontside towards the backside of the semiconductor substrate and contacts the horizontal portion of the gate electrode structure. The second vertical portion extends from the frontside towards the backside of the semiconductor substrate, contacts the horizontal portion of the gate electrode structure, and is separated from the first vertical portion by a channel region of the substrate.

Abstract: An uninterruptible power supply system is connected to a load, and the uninterruptible power supply system includes an output terminal, a first switch, a second switch, a third switch, a controller, and a protection circuit. In a first period that the load is supplied power by the power unit, the controller turns on the first switch and the third switch and turns off the second switch. In a second period that the load is supplied power by the battery unit, the controller turns off the first switch and turns on the second switch and the third switch. If at least one of the power unit and the output terminal is abnormal, or if at least one of the battery unit and the output terminal is abnormal, the third switch is turned off by at least one of the protection circuit and the controller.

Abstract: A motor and its blade unit include a blade unit made of a conical fundamental body and a plurality of blades formed around the surface of the conical fundamental body. The blades of the blade unit are multi-sectioned ones of different sizes. These blades increase water flowing speed with help of the centrifugal force produced by rotating of the blade unit, and quickly guide water to flow along the outer wall of a motor and out of the motor, not to flow reversely back to a shaft. At the same time these blades can cut impurities in water preventing the motor from clogged by impurities, increasing water flowing-out speed, lowering motor load and electricity consumption and saving motor horsepower to prolong its service life, and also possible to be combined with various types of motors for extensive use.

Abstract: A motor has a shaft with a lengthwise through hole in a center, and a guider of a semi-circular shape having plural helical leaves to increase sucking force for gas or liquid, strengthening sucking smoothness. Water current flowing through the water passageway performs heat-dispersing function when the motor operates so as to prolong the service life of the motor. A pressure-dividing ball is placed in front of the guider to divide strong current pressure into several small current pressures to be sucked by the motor to avoid turbulent current and cause idle rotation of the motor to be damaged. Then the motor surely has strong sucking force, smoothness of flowing and its service life effectively prolonged.
