Abstract: The present disclosure, in some embodiments, relates to a method of forming a capacitor structure. The method includes forming a capacitor dielectric layer over a lower electrode layer, and forming an upper electrode layer over the capacitor dielectric layer. The upper electrode layer is etched to define an upper electrode and to expose a part of the capacitor dielectric layer. A spacer structure is formed over horizontally extending surfaces of the upper electrode layer and the capacitor dielectric layer and also along sidewalls of the upper electrode. The spacer structure is etched to remove the spacer structure from over the horizontally extending surfaces of the upper electrode layer and the capacitor dielectric layer and to define a spacer. The capacitor dielectric layer and the lower electrode layer are etched according to the spacer to define a capacitor dielectric and a lower electrode.

Abstract: The present disclosure relates to an integrated chip including a dielectric structure over a substrate. A first capacitor is disposed between sidewalls of the dielectric structure. The first capacitor includes a first electrode between the sidewalls of the dielectric structure and a second electrode between the sidewalls and over the first electrode. A second capacitor is disposed between the sidewalls. The second capacitor includes the second electrode and a third electrode between the sidewalls and over the second electrode. A third capacitor is disposed between the sidewalls. The third capacitor includes the third electrode and a fourth electrode between the sidewalls and over the third electrode. The first capacitor, the second capacitor, and the third capacitor are coupled in parallel by a first contact on a first side of the first capacitor and a second contact on a second side of the first capacitor.

Abstract: A replaceable electrical ballast tube is disclosed to be applied to a lamp holder with an electrical ballast. The tube includes a capacitor, a rectifier, a current limiting unit and a light-emitting module. The capacitor is connected in parallel with the electrical ballast to filter an AC voltage generated by the electrical ballast with high frequency and high voltage. The rectifier is connected in parallel with the capacitor to rectify the AC voltage to a DC voltage. The current limiting unit converts the DC voltage to a corresponding DC current. The DC current is provided to the light-emitting module to generate light. Accordingly, the tube can be directly used in the lamp holder of a traditional fluorescent lamp without changing the wiring of the lamp holder.

Abstract: An assembly of a lighting unit and a receptacle unit includes at least one receptacle unit and at least one lighting unit. The receptacle unit has an outer housing provided with at least one first connection portion and at least one second connection portion electrically connected to the first connection portion in the outer housing. The lighting unit is electrically connected to one of the first and second connection portions of the receptacle unit, so that the lighting unit and the receptacle unit can be independently rotated in relation to each other along a connection axis thereof.

Abstract: A LED light tube is revealed. The LED light tube includes a tube-shaped heat dissipation base, a printed circuit board and a light cover. The light cover includes an outer light emitting layer, an inner light emitting layer and a hollow part formed by a gap between the inner light emitting layer and the outer light emitting layer. The inner light emitting layer of the light cover presses on the printed circuit board in order to fix the printed circuit board on the tube-shaped heat dissipation base so that there is no need to use any other components for fixing the printed circuit board on the tube-shaped heat dissipation base.

Abstract: A LED light tube and its connector thereof are revealed. Each of two ends of the LED light tube is disposed with a LED light tube connector. The LED light tube connector includes a rotating base, two connector pins, a cover and a housing. The two connector pins are disposed on one end of the rotating base. The rotating base includes a first location adjustment structure and the cover has a second location adjustment structure. The rotating base is mounted in the housing while the cover is fixed on the housing. The rotating base rotates relative to the cover as well as the housing optionally so as to adjust the assembling between the first and the second location adjustment structure. Thus the two connector pins change from a first position to a second position and light from the LED light tube emits in a desired direction.
