    摘要: A method for forming a capacitor of a semiconductor device includes the steps of forming first and second sacrificial insulation layers over a semiconductor substrate divided into first and second regions. The second and first sacrificial insulation layers in the first region are etched to define in the first region of the semiconductor substrate. Storage nodes on surfaces of the holes are formed. A partial thickness of the second sacrificial insulation layer is etched to partially expose upper portions of the storage nodes. A mask pattern is formed to cover the first region while exposing the second sacrificial insulation layer remaining in the second region. The exposed second sacrificial insulation layer in the second region is removed to expose the first sacrificial insulation layer in the second region. The exposed first sacrificial insulation layer in the second region and the first sacrificial insulation layer in the first region is removed. The mask pattern is removed. The second sacrificial insulation layer remaining in the first region is removed.

    摘要: Provided is a pixel driving circuit including a threshold voltage compensation circuit. The pixel driving circuit includes a diode-connected type first transistor through which input current data flows; a second transistor copying the current data flowing through the first transistor; a third transistor connected in series to the second transistor; a fourth transistor diode-connected between a power supply voltage terminal and the third transistor; and a driving transistor connected to the power supply voltage terminal, copying the current data flowing through the third transistor, and providing the data to a light emitting diode. Since the pixel driving circuit compensates for variation in the threshold voltage of the driving transistor driving each pixel, brightness uniformity of pixels according to applied current data can be maintained.

    摘要: A digital-to-analog converter (DAC) for a sigma-delta modulator is provided. The DAC has a switched capacitor structure using an operational amplifier (OP amp) and performs a function exceeding 3-level using a switching method employing only one capacitor in single ended form. Thus, DAC non-linearity caused by capacitor mismatching does not occur, and the number of output levels of the DAC is increased. Also, the DAC capacitor may be applied to a general DAC to increase the ratio of DAC output levels to capacitors.
