What is the difference between a "good" and a "bad" oxide?
It depends on the application and the material and whether you mean the native oxide or deliberately depositied oxides. A 'bad' oxide would be something harmful to the efficiency or lifetime etc. of the device. A good oxide would provide some beneficial effect, such as protecting the device from atmospheric contamination or acting as a dielectric,izzor said:What is the difference between a "good" and a "bad" oxide?

Oxides in semiconductor technology refer to the use of oxide materials, such as silicon dioxide, in the manufacturing of semiconductors. These oxides act as insulators and are used to create a barrier between different layers of a semiconductor device.
Oxides play a crucial role in semiconductor devices by providing insulation and allowing for the creation of different layers within the device. They also help to prevent the diffusion of impurities and enhance the performance of the device.
Oxides are typically applied in semiconductor technology through a process called thermal oxidation. This involves heating the semiconductor material in the presence of oxygen, which causes the formation of a thin layer of oxide on the surface.
There are several advantages to using oxides in semiconductor technology. These include their ability to act as insulators, their compatibility with other semiconductor materials, and their ability to improve the performance and reliability of semiconductor devices.
While oxides offer many benefits in semiconductor technology, they also have some limitations. One limitation is their tendency to trap charges, which can affect the performance of the device. Additionally, the thickness and uniformity of the oxide layer can be difficult to control, leading to variations in device performance.
