And a third impurity region 358 formed externally to the gate electrode.
A gate electrode of the transistor 550 is electrically connected to the scan line GL_m.
This overlapped portion later becomes an IDD region overlapping with the gate electrode.
A spacer over the gate electrode and sidewalls of the gate electrode;
Accordingly, charge related to new data is given to the gate electrode of the transistor 160.
The gate electrodes 524a and 524b appear to be separate from each other, but are really electrically connected together.
An insulating sidewall spacer formed on the sidewall of the gate electrode;
In the case of forming the gate electrode and the antenna at the same time, the material may be selected in consideration of these functions.
Common potential lines 1554 and 1555 connected to the diodes are formed in the same layer as the gate electrode.
Forming a gate line, a gate pad and a gate electrode on a reflective substrate;
Forming a gate electrode having a taper portion by selectively etching the conductive layer;
Thus, it is desirable that the LDD region 357 is made to completely overlap the gate electrode to decrease a resistance component to a minimum.
In the case of forming the gate electrode and the antenna at the same time, the material may be selected in consideration of these functions.
Therefore, it is desirable that the LDD region 37 is completely overlapped with the gate electrode and the resistance component is reduced as much as possible.
Forming a gate electrode, a source wiring of the pixel portion, and an electrode of the terminal portion on the first insulating film;
This second p-channel TFT(B) 202 b is a triple gate structure in which three gate electrodes are formed between a pair of source/drain region.
In this structure, since the gate electrode is etched in a tapered shape or anisotropic etching is used, it is difficult to control the width of the LDD region, and the LDD region may not be formed unless the etching process is appropriately performed.
A, an n-type impurity element(phosphorus in this embodiment) is added in a self-aligning manner using the gate electrodes 312 to 316 as masks.
In addition, since contribution of the electric field of the gate electrode can be increased, the off-state characteristics of the transistor 2200 can be improved.
An insulating film serving as a base film may be provided between the substrate 394 and the gate electrode layer 391.
A fifth step of forming a gate electrode having a taper portion by selectively etching the conductive layer;
According to the present invention, in order to protect the device from deterioration due to light, a color filter(R)is formed below the gate electrodes of the TFTs, that is, below the channel forming regions.
Further, since the P floating region facing the gate electrode 22 is not provided, problems such as the influence of ion implantation and increase in on-resistance do not occur.
Next, the current control TFT 202 includes an active layer including a source region 31,a drain region 32, an LDD region 33, and a channel formation region 34, a gate insulating film 18, a gate electrode 35, a first interlayer insulating film 20, a source wiring 36, and A drain wiring 37 is formed.
This is because if oxygen exists even in a small amount, the exposed surface of the gate electrode is oxidized to cause the increase of resistance, and also it becomes difficult to make ohmic contact later.
E, the light absorption layer 4006 is shaped by etching, a conductive film is formed over the light absorption layer 4006, and further the conductive filmis shaped by etching; thus, the gate electrode 4008 having two or more layers can also be formed.
This is because if oxygen exists even in a small amount, the exposed surface of the gate electrode is oxidized to cause the increase of resistance, and also it becomes difficult to make ohmic contact later.
On the other hand, in the case where the characteristics of the transistor 560 have priority, sidewall insulating layers may be provided on side surfaces of a gate electrode 524a, and the impurity regions 528 may each include a region with a different impurity concentration in a region overlapping with the sidewall insulating layer.
In the present Embodiment 4, the materials or the formation steps, for example, of the gate electrodes 9 of the nMISQn and pMISQp are the same as those of the gate electrodes 9 in the memory cell region, and, thereby, the number of steps can be reduced.
