Introduction to Very Large Scale Integration (VLSI) Technology

Introduction to Very Large Scale Integration (VLSI) Technology

Structure of the transistor:

       The cross-section of an n-type MOS transistor as shown in fig.-1 an n-type transistor is embedded in a p-type substrate; it is formed by the intersection of an n-type wire and a polysilicon wire. The region at the intersection called the channel, is where the transistor action takes place. The channel connects to the two n-type wires, which form the source and drain, but is itself doped to be p-type. The insulating silicon dioxide at the channel (called the gate oxide) is much thinner than it is away from the channel (called the field oxide); having a thin oxide at the channel is critical to the successful operation of the transistor.

                            Fig.-1: Cross-section of an n-type transistor.
         The transistor works as a switch because the gate-to-source 
voltage modulates the amount of current that can flow between the source
and drain. When the gate voltage (Vgs) is zero, the p-type channel is full of 
holes, while the n-type source and drain contain electrons. The p-n 
junction at source terminal forms a diode, while the junction at the drain 
forms a second diode that conducts in the opposite direction. As a result,
no current can flow from the source to the drain.
         As  Vgs  rises above zero, the situation starts to change. While the 
channel region contains predominantly p-type carriers, it also has some 
n-type carriers. The positive voltage on the polysilicon which forms the 
gate attracts the electrons. Since they are stopped by the gate oxide, 
they collect at the top of the channel along the oxide boundary. At a 
critical voltage called the threshold voltage (Vt), enough electrons 
have collected at the channel boundary to form an inversion layer-a 
layer of electrons dense enough to conduct current between the 
source and the drain.
         The size of the channel region is labeled relative to the direction of 
current flow: the channel length (L) is along the direction of current
flow between source and drain, while the width (W) is perpendicular to 
current flow. The amount of current flow is a function of the W/L ratio, 
for the same reasons that bulk resistance changes with the object’s width 
and length: widening the channel gives a larger cross-section for 
conduction, while lengthening the channel increases the distance, current 
must flow through the channel. Since we can choose W and L when we 
draw the layout, we can very simply design the transistor current 

Drain current characteristics:

For an n-type transistor, we have:

   Linear region ( Vds < Vgs – Vt ):
        Id = k’(W/L)[(Vgs-Vt)(Vds-0.5Vds2)]
 Saturation region (Vds ≥ Vgs - Vt):
        Id =0.5k’(W/L)(Vgs- Vt)2(W/L) = the width-to-length ratio of the transistor.

Both  Vt  and k’ are measured, either directly or indirectly, for fabrication a process, W/L is determined by the layout of the transistor, but since it does not change during operation, it is a constant of the device equations.

0.5 mm transconductances:

From an MOSIS process:
k’n = 73 mA/V2           where,    Vt = 0.7 V

k’p = 21 mA/V2,         where,     Vt = -0.8 V

Current through a transistor:

Use 0.5 mm parameters. Let W/L = 3/2. Measure at the boundary between 
linear and saturation regions.

Vgs = 2V:     Id = 0.5k’(W/L)(Vgs-Vt)2= 93 mA

Vgs = 5V:     Id = 1 mA

Parallel plate capacitance:

1.     Formula for parallel plate capacitance:       
       Cox = eox / xox
2.     Permittivity of silicon:      
       eox = 3.46 x 10-13 F/cm2
3.     Gate capacitance helps determine charge in channel which forms 
       inversion region.

Threshold voltage

1.     Components of threshold voltage Vt:
2.     Vfb = flat band voltage; depends on difference in work function between 
       gate and the substrate and on fixed surface charge.
3.     fs = surface potential (about 2ff).
4.     The Voltage on parallel plate capacitor.
5.     Additional ion implantation.

Body effect

1.     Reorganize threshold voltage equation:   
      Vt = Vt0 + DVt
2.     The threshold voltage is a function of source/substrate voltage Vsb.
3.     Body effect g is the coefficient for the Vsb dependence factor.


Example: threshold voltage of a transistor

Vt0 = Vfb + fs + Qb/Cox + VII
  = -0.91 V + 0.58 V + (1.4E-8/1.73E-7) + 0.92 V
  = 0.68 V

Body effect gn = sqrt(2qeSiNA/Cox) = 0.1
DVt = gn[sqrt(fs + Vsb) - sqrt(Vs)]
        = 0.16 V


1.     Process transconductance k’ = mCox.
2.     Device transconductance b = k’W/L.


a.     Describes a small dependence of drain current on Vds in saturation.
b.    The Factor is measured empirically.
c.      New drain current equation:
      Id = 0.5k’ (W/L)(Vgs - Vt2(l l Vds)
d.     Equation has a discontinuity between linear and saturation 
      regions---small enough to be ignored.


 Basic transistor parasitics

a.     Gate to the substrate and Gate to source/drain.
b.     Source/drain capacitance, resistance.

c.     Gate capacitance Cg. Determined by active area.
d.     Source/drain overlap capacitances Cgs, Cgd
      Determined by source/gate and drain/gate overlaps. Independent of 
      transistor L.  Cgs = Col W
e.      Gate/bulk overlap capacitance.


a.     CMOS ICs have parasitic silicon-controlled rectifiers (SCRs).

b.     When powered up, SCRs can turn on, creating low-resistance path 
       from power to ground. Current can destroy the chip.

c.      Early CMOS problem. Can be solved with proper circuit/layout 

Match after 33 years of immortality!

For the next 33 years in the Russian media, mogul Dmitry Itskov is seeking to create a mechanical immortality. This is completely out of holographic 'Human avatar'. For this group of scientist are appointed by the Itskov. For this project the world's leading mechanical brain is rich in rich man's help, he means. Itskov's demand, over the next 33 years will be achieved within a few steps cybernetic immortality. The first will be to create a robot that can be used to control the interface with the brain. Then, another robot will be created, which can replace the human brain. The next step will be to create another robot, a machine which imitates the human brain's biological brain. 

And everyone will be created at the end of a holographic 'avatar', where the human intelligence. The financing to create for the project, Itskov wrote an open letter to the Forbes magazine world's top rich man according. They also wanted to achieve immortality, said his opened letter. Not only so, he expressed doubts about the performance of the project, its performance in front of them, and to take part in the project that they had declared. The day after 33 years mogul Dmitry Itskov will achieve immortality in the world.  For his declaration, interest has been created by the Russian media. Though Dmitry Itskov is the Russian media mogul, so sure but the issue of his personal life and the past period is very mysterious. At 2045, if the demand in Itskov cybernetic way to achieve immortality was successful, but the Hollywood movie 'surrogate' - The real story that will leave from cinema screen, it goes without saying.

The neck spandelaitis, back pain, foot pain, shoulder pain, I always heard these from the computer users.But what should be done to live? The people who work in the computer through the livelong multinational company is to work. But these medical problems and fear of what they leave a job? In some ways, you should not have to live. Now I tell you the ways through this you can save yourself from the physicals problems.

 Be Safe When Using The Computer : 

Important Steps.

1. Do not look at the computer screen for a long time.
2 .Every 10 minutes blink your eye. Blink in the comfort of your eye.
3. Sometimes give water spray in your eyes. 

4. Get up from the chair and go outside for five minutes at best.
5. Spin your neck - Left turn right. The neck should be exercising.
