Yes, dry oxidation technique is commonly used for forming field oxide in semiconductor device fabrication. It involves exposing a silicon wafer to oxygen at high temperatures, leading to the growth of a thin silicon dioxide layer that serves as an insulating field oxide. This technique is preferred for its controlled and uniform oxide growth.
What else can I help you with?
What does iron have to be exposed to for oxidation to occur?
Iron has to be exposed to oxygen for oxidation to occur.
What does the existence of Cu2Oand CuO illustrates?
The existence of both Cu2O and CuO demonstrates the ability of copper to form multiple oxidation states depending on the conditions. Cu2O is copper(I) oxide, where copper has a +1 oxidation state, while CuO is copper(II) oxide, where copper has a +2 oxidation state. This highlights the flexibility of copper in forming different compounds.
What is copper in a plus 2 oxidation in cupric oxide?
The chemical formula of cupric oxide is CuO.
Copper 2 oxide formula?
The chemical formula for copper (II) oxide is CuO. In this compound, copper is in the +2 oxidation state and oxygen is in the -2 oxidation state.
What type of reaction occurs when iron mixes with oxygen?
it forms iron oxide, and it can/should form rust
Rust is formed as a result of oxidation of which metal?
Rust is formed as a result of oxidation of iron (Fe) metal.
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.
What is the oxidation number of N O?
The oxidation number of NO, nitrogen oxide, is +3.
What does iron have to be exposed to for oxidation to occur?
Iron has to be exposed to oxygen for oxidation to occur.
How can iron form two separate compounds with oxygen?
Iron can form two different ions, Fe2+ and Fe3+. Because of their different charges these ions will bond differently with anions such as oxide (O2-) As a result we get the compounds FeO and Fe2O3. There is a third oxide which is a combination of the two: Fe3O4
What does the existence of Cu2Oand CuO illustrates?
The existence of both Cu2O and CuO demonstrates the ability of copper to form multiple oxidation states depending on the conditions. Cu2O is copper(I) oxide, where copper has a +1 oxidation state, while CuO is copper(II) oxide, where copper has a +2 oxidation state.

What is the oxidation state for oxygen in oxide ion?
The oxidation state for oxygen in the oxide ion (O2-) is -2. Oxygen typically has an oxidation state of -2 in most of its compounds.
What is the oxidation number of potassium in potassium oxide?
The oxidation number of potassium in potassium oxide is +1. Potassium is an alkali metal that typically has a +1 oxidation state when it forms compounds.
What is the oxidation number of Mn in manganese VII oxide?
The oxidation number of Mn in manganese VII oxide is +7. This is because oxygen typically has an oxidation number of -2, and there are two oxygen atoms in manganese VII oxide, giving a total oxidation number of -4. To balance the compound's charge of 0, manganese must have an oxidation number of +7.
What is the change in oxidation number for lithium oxide?
The oxidation number for lithium is +1 and for oxygen is -2. In lithium oxide (Li2O), lithium has an oxidation number of +1 and oxygen has an oxidation number of -2. Therefore, the change in oxidation number for lithium oxide is -1 for lithium.
Why does a black colour come when you put a copper coin on yop of a Bunsen flqme?
When a copper coin is heated on a Bunsen flame, it undergoes oxidation, forming copper oxide. Copper oxide is a black compound, which is why the coin appears black.
What is the oxidation number of iron(II) oxide?
I am going to assume you meant ferrous oxide. Ferrous oxide is also known as Iron(II) oxide and has the formula unit FeO. The oxidation number of iron in iron(II) oxide is +2.
