Addition of suitable impurities into semiconductor, is called A. Doping B. Mixing C. Forming D. Diluting

Doping
Mixing
Forming
Diluting

The correct answer is A. Doping.

Doping is the process of adding impurities to a semiconductor in order to change its electrical properties. The impurities are called dopants, and they can be either donors or acceptors. Donors are atoms that have more valence electrons than the semiconductor atoms, and they donate these electrons to the semiconductor. Acceptors are atoms that have fewer valence electrons than the semiconductor atoms, and they accept electrons from the semiconductor.

The addition of dopants can change the conductivity of the semiconductor. For example, adding a donor impurity to an n-type semiconductor will increase its conductivity, while adding an acceptor impurity to an n-type semiconductor will decrease its conductivity.

Doping is a very important process in the manufacture of semiconductor devices, such as transistors and integrated circuits. It is used to control the electrical properties of these devices, and it is essential for their proper operation.

Here is a brief explanation of each option:

  • A. Doping: The process of adding impurities to a semiconductor in order to change its electrical properties.
  • B. Mixing: The process of combining two or more substances to form a new substance.
  • C. Forming: The process of creating a new object or structure.
  • D. Diluting: The process of making something less concentrated by adding more of a different substance.
