A thin-film transistor is provided in which the thickness of the insulating film is optimized. A gate electrode is formed on a transparent substrate. A silicon nitride film and a silicon oxide film, acting as a gate insulating film, are formed over the transparent substrate. A polycrystalline silicon film, being a semiconductor film, is formed acting as an active region. A stopper is formed on the polycrystalline silicon film corresponding to the gate electrode. A silicon oxide film and a silicon nitride film, acting as an interlayer insulating film, are deposited as to cover the stopper region. The total film thickness T1 of the stopper and the silicon oxide film is formed to be thinner than (the thickness T2 of the silicon nitride film×8000 Å)½. This structure allows hydrogen atoms to be sufficiently supplied from the silicon nitride film into the polycrystalline silicon film via the stopper and the silicon oxide film, so that crystalline defects in the polycrystalline silicon film can be filled with the hydrogen atoms.

A single shared line (VLc) is provided as a power source line (VL) between two display pixels disposed adjoining each other in a row direction. Such a layout with the shared line (VLc) makes it possible to set the width of the shared line (VLc) equal to the sum of twice the width (Wd) of the power source line and the space (Ws) between the lines, even with the area of a single pixel is the same as in a conventional design. As a result, an increase in line resistance of the power source line can be suppressed, and variation in display luminance in accordance with the distance from a power source terminal due to a voltage drop can be reliably reduced.

Thin film transistors TFT2a and TFT2b for driving elements are formed in parallel between a power source line (16) and an organic EL element (60), and active layers (12) of the transistors TFT2a and TFT2b are spaced apart in a scanning direction of a laser used for annealing for polycrystallization. As a result, the annealing conditions for the transistors TFT2a and TFT2b will not be exactly the same, thereby reducing the chance of a same problem being caused in both transistors TFT2a and TFT2b.

There is provided an input/output device having of not exerting any adverse influence on other expansion devices connected to a system bus at the time of insertion or removal. An expansion device 800 comprises an electronic circuit 400 and a MOS switch 300, and is connected to a system bus (BUS) via a connector having long and short pins. The expansion device 800 two power supply systems, namely a stable power supply 250 and an unstable power supply 260. At the time of insertion or removal of the expansion device 800, power is provided to the MOS switch 300 and a high impedance maintaining circuit from the stable power supply via a pair of long pins, so as to reliably place the MOS switch 300 in a high impedance state, inside the expansion device the high impedance maintaining circuit 350 drives an open/close control terminal, and power is provided to the electronic circuit 400 from the unstable power supply 260. At the time of insertion or removal, adverse influence is not exerted on the signal transmission on the system bus, and effects of load variation on the main power supply are reduced.
摘要:
For obtaining p-Si by irradiating a laser beam to an a-Si layer to polycrystallize, an energy level in a region to be irradiated by the laser beam is set such that a level at the rear area of the region along a scan direction of the laser beam is lower than that at the front area or the center area of the region. The energy level at the front area or the center area of the region is set such that it is substantially equal to or more than the upper limit energy level which maximizes a grain size of the p-Si obtained. since an energy profile is set as described above, when the laser beam is scanned on the a-Si layer, an irradiated energy of the laser on the region is gradually lowered from the upper limit as the laser beam passes through, which allows the semiconductor layer to be annealed within an optimal energy level during the latter half of the annealing process.
摘要:
A gate electrode (2), a gate insulating film (3), and an active layer (4) made of a poly silicon film and having a source (5), a channel (7), and a drain (6) are formed on an insulating substrate (1) and an interlayer insulating film (9) is formed over the whole of the gate insulating film (3), the active layer (4), and a stopper insulating film (8). A drain electrode (10) is formed by filling a contact hole made in the interlayer insulating film (9), the position of which corresponds to the drain (6), with a metal, such as Al. Simultaneously with the drain electrode (10), a conductive layer (11) is formed on the interlayer insulating film (9) over the channel (7). The conductive layer (11) is connected to gate signal line G on the insulating substrate (1) via a contact hole (15) made in the gate insulating film (3) and the interlayer insulating film (9). The width of the conductive layer (11) along the length of the channel (7) is narrower than the actual length of the channel (7) and narrower than the width along the channel length of the gate electrode (2). The conductive layer (11) can therefore shield the channel (7). As a result, even if impurities or the like become attached to the surface of the interlayer insulating film (9), the occurrence of a back channel, for example, is reliably prevented.

In a method of tightening a screw member, the difference between the tightening axial force which is produced at the limit of elasticity when the friction coefficient between the screw member and a member into which the screw member is to be threaded is at a maximum and that when the friction coefficient between the screw member and the member into which the screw member is to be threaded is at a minimum is calculated, a seating torque is determined on the basis of the difference between the tightening axial forces, the screw member is threaded into the member into which the screw member is to be threaded until the tightening torque reaches the seating torque, and then the screw member is tightened by a predetermined angle.

This disclosure relates to a rotary kiln for heating and calcining lime, waste, etc. and to a method of direct reduction of metal oxide using such a kiln. A cylindrical outer shell is mounted for rotation on its axis, and a stationary inner tube extends into the interior of the shell. Fuel and/or combustion air flow passages extend within the tube, and burner nozzles are supported by the tube and are connected to the passages. The tube is concentrically or eccentrically mounted adjacent the upper side of the space within the shell, thereby positioning the burner nozzles at the optimum positions.
摘要:
Static bed type iron oxide reducing apparatus comprises reduction furnaces and cooling chambers respectively associated with the furnaces. Iron oxides are charged into the furnaces and reducing gas is applied to the raw materials to carry out a reducing reaction. After the iron oxides in the furnace have been metallized to a sufficient level, they are transferred to the cooling chamber to be cooled therein.
