What is silicide?

What is silicide?

Silicide (compound of silicon with metal) is formed on gates (polysilicon), sources and drains (Si wafer) as three MOS transistor electrodes in order to reduce contact resistance to metal wiring layers to be formed later. This silicide formation also has the effect of lowering the resistance of each electrode.

What is the symbol for silicide?

Why are silicides used?

Abstract. Metallic silicides and germanides are used as contact materials on source/drain and gate in metal oxide semiconductor (MOS) structures such as transistors or memories. They are fabricated by reaction between a metal or a metallic alloy thin film and the Si (Ge) substrate.

What is silicide VLSI?

Silicides have become widely used in VLSI processing in order to avoid the increase in resistance otherwise associated with reduced polysilicon linewidths and film thicknesses. This is illustrated by examining the relationship between simulated gate delay per stage, as shown in Figure 1.

What is a silicide and how is it formed?

From Wikipedia, the free encyclopedia. A silicide is a type of chemical compound that combines silicon and a (usually) more electropositive element. Silicon is more electropositive than carbon. Silicides are structurally closer to borides than to carbides.

Definition of disilicide. : a compound containing two atoms of silicon combined with an element or radical.

What is the meaning of being respectful to others?

Consequently, the common meaning of respect is to behave as other people feel you should behave. If you violate others’ expectations in certain ways, then you’re being disrespectful. If you behave the way others feel you should behave, then you’re being respectful.

What is the origin of the word respect?

The Latin origin of the word respect also means “to look back.” Respect is just observation. To respect a belief is to observe it — to acknowledge its existence. So the word respect doesn’t actually pack a lot of punch. It really just means looking at another person’s beliefs.
