Abstract: An object is to reduce leakage current and parasitic capacitance of a transistor used for an LSI, a CPU, or a memory. A semiconductor integrated circuit such as an LSI, a CPU, or a memory is manufactured using a thin film transistor in which a channel formation region is formed using an oxide semiconductor which becomes an intrinsic or substantially intrinsic semiconductor by removing impurities which serve as electron donors (donors) from the oxide semiconductor and has larger energy gap than that of a silicon semiconductor. With use of a thin film transistor using a highly purified oxide semiconductor layer with sufficiently reduced hydrogen concentration, a semiconductor device with low power consumption due to leakage current can be realized.

Abstract: A FET is formed on a semiconductor substrate, a curved surface having a radius of curvature is formed on an upper end of an insulation, a portion of a first electrode is exposed corresponding to the curved surface to form an inclined surface, and a region defining a luminescent region is subjected to etching to expose the first electrode. Luminescence emitted from an organic chemical compound layer is reflected by the inclined surface of the first electrode to increase a total quantity of luminescence taken out in a certain direction.

Abstract: An object is to provide a semiconductor device having a structure with which parasitic capacitance between wirings can be sufficiently reduced. An oxide insulating layer serving as a channel protective layer is formed over part of an oxide semiconductor layer overlapping with a gate electrode layer. In the same step as formation of the oxide insulating layer, an oxide insulating layer covering a peripheral portion of the oxide semiconductor layer is formed. The oxide insulating layer which covers the peripheral portion of the oxide semiconductor layer is provided to increase the distance between the gate electrode layer and a wiring layer formed above or in the periphery of the gate electrode layer, whereby parasitic capacitance is reduced.

Abstract: As a result of miniaturization of a pixel region associated with an improvement in definition and an increase in a substrate size associated with an increase in area, defects due to precision, bending, and the like of a mask used at the time of evaporation have become issues. A partition including portions with different thicknesses over a pixel electrode (also referred to as a first electrode) in a display region and in the vicinity of a pixel electrode layer is formed, without increasing the number of steps, by using a photomask or a reticle provided with an auxiliary pattern having a light intensity reduction function made of a diffraction grating pattern or a semi-transmissive film.

Abstract: To provide a light emitting device high in reliability with a pixel portion having high definition with a large screen. According to a light emitting device of the present invention, on an insulator (24) provided between pixel electrodes, an auxiliary electrode (21) made of a metal film is formed, whereby a conductive layer (20) made of a transparent conductive film in contact with the auxiliary electrode can be made low in resistance and thin. Also, the auxiliary electrode (21) is used to achieve connection with an electrode on a lower layer, whereby the electrode can be led out with the transparent conductive film formed on an EL layer. Further, a protective film (32) made of a film containing hydrogen and a silicon nitride film which are laminated is formed, whereby high reliability can be achieved.

Abstract: In a display device such as a liquid crystal display device, a large-sized display screen is realized under low power consumption. A surface of a source wiring line of a pixel portion employed in an active matrix type liquid crystal display device is processed by way of a plating process operation so as to lower a resistance value of this source wiring line. The source wiring line of the pixel portion is manufactured at a step different from a step for manufacturing a source wiring line of a drive circuit portion. Further, electrodes of a terminal portion are processed by a plating process operation so as to reduce a resistance value thereof.
