      Hi,

      they are mainly silicon with small amounts of boron and phosphorous.

      They are arranged into transistors, which are devices that sometimes permit electrons to flow through and other times do not.

      Dear Little M
      Thanks for the brilliant question
      It composes of something call (semiconductor). A semiconductor is a material which has electrical conductivity between that of a conductor such as copper and that of an insulator such as glass. Semiconductor is mostly silicon, germanium, and compounds of gallium are the most widely used in electronic devices. Semiconductor conducts current through the movement of free electrons and “holes”, collectively known as charge carriers.
      Hopefully this answer is clear
      Again thanks
      Ahmed
