What is breakdown mechanism in the semiconductor diode?
a conductor which doped interncily i.e doped externaly is semiconductor m=1/1-(v/vbd)n m=multipulfactors v=applied revese voltage vbd=break down reverse voltage n= emperical constant n=4 for n-type si n=2 forp-type si
Is cmos is static complementary logic?
No. CMOS stands for Complementary Metal Oxide Semiconductor. Basically, it is a transistor formed by semiconductor bar to which an electrode (gate) attaches. This gate is isolated from the bar. A voltage on the the gate will create an electrostatic field that will prevent the current to circulate along the semiconductor bar. CMOS transistors are mostly used for digital (binary) application and consume very little current.
What are the types of breakdown region in diode?
zener breakdown and avalanche breakdown.
Definition of a capacitance in mosfet?
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.
Which gate is equivalent to bubbled AND gate?
nand gate
Why MOSFET breakdown during normal handling?
Human body have electrostaticelectricity and MOSFET are made with Field Effect Transistor, a kind of transistor very sensitive to electricity including electrostatic. Specifically, MOSFETs have a very thin gate oxide layer, which insulates the gate from the source and drain. Exceeding the gate voltage limit can "punch a hole" in the oxide layer, so to speak, causing permanent damage to the device. The gate oxide is much more sensitive to electrostatic discharge than the source/drain junctions.

What chemicals does limestone breakdown to when heated?
calcium oxide (quicklime) and carbon dioxide
What is tunneling effect in cmos?
If gate oxide is very thin then electrons in channel may enter into oxide region. This is called tunneling
How do you access ammo?
According to recent surveys in order to access ammo you just breakdown the stinkin gate!!
What a difference between dry and wet oxidation?
Dry oxidation has a lower growth rate than wet oxidation although the oxide film quality is better than the wet oxide film. Therefore thin oxides such as screen oxide, pad oxide, and especially gate oxide normally use the dry oxidation process. Dry oxidation also results in a higher density oxide than that achieved by wet oxide and so it has a higher breakdown voltageIn case of wet oxidation where water is use instead of oxygen, the water molecule can dissociate at high temperatures to form hydroxide OH that can diffuse in the silicon faster than molecular O2. Therefore the wet oxidation process has a significantly higher oxidation rate than the dry oxidation. It is used to grow thick oxides such as masking oxide, blanket field oxide, and the LOCOS oxide.
Which enzyme is responsible to the breakdown of hydrogen peroxide?
Manganese oxide is a catalyst which speeds up the decomposition of hydrogen peroxide.
Why is MOSFET called IGFET?
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
What is the influence of gate voltage on drain source breakdown voltage in mos transistors?
Drain-to-source breakdown voltage (BVdss) should not change appreciably until the gate-to-source voltage (Vgs) approaches the device's threshold voltage (Vth). In that case, the drain to source voltage becomes the product of the drain-to-source current (Ids) and the device's on-state resistance (Rds-on) at the given Vgs.
Why silicon oxide is used in mosfet gate?
becoz it is very cheaper than germanium and also it is mainly used inducing negative ions (electrons ).
Is rust forming on the metal gate is a physical or chemical change?
Rust forming on a metal gate is a chemical change. It is a result of a chemical reaction between iron, oxygen, and water, which leads to the formation of iron oxide (rust).
How mosfet works inspite of insulator under the gate how the gate attracts or rpels the charge carriers from substrate to form a channel?
For the Proper operation of NMOS Transistor Substrate and Source are connected to the Lower potential, If we are applying a positive Gate voltage with respected to Source Similarly The gate voltage is positive to Substrate Hence due to the body voltage, electrons are accumulated under the oxide layer and forming a channel for conduction.
