    摘要: A semiconductor device includes a first active pattern on a substrate; a first gate electrode crossing the first active pattern; source/drain patterns in an upper portion of the first active pattern and at opposite sides, respectively, of the first gate electrode; a first gate capping pattern on the first gate electrode; an interlayer insulating layer on the source/drain patterns; first and second active contacts penetrating the interlayer insulating layer and being respectively connected to the pair of source/drain patterns; and a first interconnection layer on the first and second active contacts. The first interconnection layer may include a first insulating structure covering a top surface of the second active contact; and a first interconnection line covering a top surface of the first active contact and extending on the first insulating structure, and covering a top surface of the first gate capping pattern between the first and second active contacts.

    摘要: An image sensor includes a pixel sensor that senses an incident light and outputs a sampling signal of an analog shape, a sampler that compares the sampling signal and a ramp signal and outputs a comparison signal being time-axis length information, and a gray counter that counts a length of the comparison signal in synchronization with a clock signal and outputs a digital value. The gray counter includes a first flip-flop that divides the clock signal by 2 and generates a first gray code signal, a second flip-flop that delays a first data signal being a four-divided signal of the clock signal and outputs a second gray code signal, and a third flip-flop that delays the second gray code signal being two-divided and outputs a third gray code signal.

    摘要: A controller is for controlling a battery module including a plurality of battery cells in a housing. The controller includes a control module to perform at least one control function with respect to at least one of the plurality of battery cells; and an access detection circuit including a light sensitive element in the housing. The access detection circuit is to output an access detection signal when a light intensity in the housing is greater than a predetermined threshold. The controller is to alter a state of the control module in response to the access detection signal.
