Semiconductor device, display device and electronic device equipped with the semiconductor device
InactiveUS20070035340A1Reduce power consumptionAvoid flowImpedence convertorsElectroluminescent light sourcesCapacitanceElectrical resistance and conductance
The present invention provides a semiconductor device which can prevent a current from flowing into a display element at a signal writing operation, without increasing power consumption and without changing a potential of a power supply for supplying a current to a load in each row. When a predetermined current is supplied to a transistor to set a gate-source voltage of the transistor, a potential of a gate terminal of the transistor is adjusted so as to prevent a current from flowing into a load which is connected to a source terminal of the transistor. Thus, a potential of a wire connected to the gate terminal of the transistor is made different from that of a wire connected to a drain terminal of the transistor. At that time, an operation of a transistor is shifted so as to allow a large amount of current to flow, and influences by intersection capacitance parasitic to a wire or the like or wire resistance are hardly caused, and a set operation is conducted quickly.

Stress level of a nitride film is adjusted as a function of two or more of the following: identity of a starting material precursor used to make the nitride film; identity of a nitrogen-containing precursor with which is treated the starting material precursor; ratio of the starting material precursor to the nitrogen-containing precursor; a set of CVD conditions under which the film is grown; and / or a thickness to which the film is grown. A rapid thermal chemical vapor deposition (RTCVD) film produced by reacting a compound containing silicon, nitrogen and carbon (such as bis-tertiary butyl amino silane (BTBAS)) with NH3 can provide advantageous properties, such as high stress and excellent performance in an etch-stop application. An ammonia-treated BTBAS film is particularly excellent in providing a high-stress property, and further having maintainability of that high-stress property over repeated annealing.
